StorageWorks Website The StorageWorks website has the latest information on this product, as well as the After the controller is initially configured and made visible to the host, other configuration tasks can be performed through this remote connection. The resulting display shows an overview of the CLI Help System. If a specific command specifies parameter names, they must be entered in the command string.This section contains the CLI command descriptions that contain the description, full syntax, and examples of the use of each command available on the CLI interface. This command adds an association set to the controller pair’s configuration. The association set can be initialized with a single remote copy set through the use of the remote-copy-set-name switch. Another storageset can then be added to the concatset by the SET CONCATSETS command, thereby dynamically increasing the size of the unit. This command adds the specified host connection to the table of known connections. This table is maintained in the controller’s memory. The connection-name may consist of a maximum of nine printable characters excluding commas and back-slashes. The controller automatically assigns default connection name when a connection is physically made between a host adapter and a controller port. This command adds a !NEWCONxx connection to the connection table in an OFFLINE state. This is the number by which the unit is known internally to the controllers. For example, a system has three host connections, each of which can see 8 LUNs. This command is typically used when disk drives are added to a previously configured subsystem. During initial setup, the entire disk set is customarily added to the controller’s configuration by issuing the RUN CONFIG command. If you specify TRANSPORTABLE for a disk that was originally initialized as a NOTRANSPORTABLE, you should initialize the disk. Mirrorsets are often referred to as RAID 1 storagesets.

The data capacity of a RAID 1 is determined by the storage size of the smallest member (base member size).This command is typically used when pass through devices are added to a previously configured subsystem. During initial setup, the entire device set is customarily added to the controller’s configuration through the CONFIG utility. RAIDsets can contain from 3 to 14 members.The controller uses relatively few resources to perform the reconstruct process and there is little impact on performance.The units may be a single disk (JBOD) or a stripeset, mirrorset, or RAIDset. NOTE: This command works only in a DRM environment and requires an HSG80 array controller with ACS version 8.7P code. This unit cannot be involved in a snapshot, and must not be a concatset.The snapshot unit can be manually presented to the host. The snapshot unit remains until it is deleted (DELETE command). Syntax ADD SPARESETS disk-name Parameters disk-name Indicates the name of the disk drive being added to the spareset. Only one disk drive can be added to the spareset with each ADD SPARESETS command. A stripeset can contain from 2 to 24 members. Stripesets are also referred to as RAID level 0 storagesets. The number of members in the stripeset is determined by the number of container-name parameters specified. Examples To create a stripeset named STRIPE1 that contains disks DISK10000, DISK20100, and DISK30200, enter: ADD STRIPESETS STRIPE1 DISK10000 DISK20100 DISK30200 To create a logical unit from STRIPE1, enter: INITIALIZE STRIPE1 ADD UNITS D103 STRIPE1 To create a two-member striped mirrorset (a stripeset whose members are mirrorsets),. The controller maps all requests from the host to the logical-unit number as requests to the container specified in the ADD UNITS command.This number maps to one or more host-accessible LUNs. How units are assigned to ports depends on the failover mode. A unit can consist of a maximum of 48 devices.

The controller will not cache any transfers over the size set. Acceptable values are 0 through 2048.The controller write-back caching feature improves write performance.Errors are displayed (even after the error condition has been rectified) until the controller is restarted or this command is entered. NOTE: This command does not clear the error condition. The command only stops the CLI from displaying the error. If the error is due to a mirrored-cache configuration that is incorrect, the controller indicates mirrored mode status after the error is cleared.The controller metadata synchronizes with the cache module data and preserves any unwritten data for eventual flushing to the disk array.A device failure may cause the controller to label the device as unknown. When that happens, the controller does not check the device again to see if it has been repaired or if the error condition has been corrected. All partitions on the unit’s container are affected. The controller reports a lost data error on the unit when you remove a write-back cache module or when the cache module contains unflushed data, possibly due to an interruption in the primary power source with no backup power present. This command affects all partitions on the same container. If a storageset or disk drive fails before its data has been written to it, the controller reports an unwriteable data error. This command causes a reboot and takes effect immediately. Switches There are no switches associated with this command. Example To restore the subsystem configuration into the memory of the controller in a single-controller subsystem, enter: CONFIGURATION RESTORE See Also CONFIGURATION RESET CONFIGURATION SAVE INITIALIZE. This allows you to know exactly when a copy of the configuration is saved. The command takes effect immediately.The command marks a specified percentage of a disk drive or storageset to be used as a separately addressable unit—a partition.

Any non-transportable disk or storageset can be divided into a maximum of eight partitions, then each partition can be separately presented to the host. NOTE: This command works only in a DRM environment and requires an HSG80 array controller with ACS version 8.7P code. Like all DRM commands, use of this command is heavily restricted. If the concatset is associated with a unit, the unit must be deleted before deleting the concatset. Syntax DELETE concatset-name Parameters concatset-name The name of the concatset to be deleted. Switches There are no switches associated with this command. Examples To delete concatset C1, which is associated with unit D0, enter: DELETE D0. The table of known host connections is maintained in the controller’s memory. Once a connection is added to the table, it stays there, even if the physical connection between host adapter and controller port is severed. IMPORTANT: A container cannot be deleted if the container is in use by a higher-level container. For example, a disk belonging to a member of a RAIDset, or a RAIDset unit, cannot be deleted. Upon completion of this command, the target unit will no longer be a member of the remote copy set. NOTE: This command works only in a DRM environment and requires an HSG80 array controller with ACS version 8.7P code. The spareset contains disk drives that are available for use, but not yet added to the controller configuration. Syntax DELETE SPARESETS disk-name Parameters disk-name Identifies the disk drive being deleted from the spareset. Remove only one disk at a time from a spareset. The DELETE command causes the flushing of any user data from the write-back cache to the disks and deletes the specified unit. The command deletes the association of the unit with its underlying device, storageset, RAIDset, or partition. The container and any data in it are left intact. Marks the area reserved for a partition as available. The available area is then consolidated with any adjacent free areas.

Switches There are no switches associated with this command. Example To display a directory listing, enter: DIRECTORY The following is an example of the resultant display: HSUTIL. Use of this command exits the CLI program and returns control to the host. Syntax EXIT Parameters There are no parameters associated with this command. Switches There are no switches associated with this command. Syntax HELP Parameters There are no parameters associated with this command. Switches There are no switches associated with this command. During initialization, a small amount of disk space is reserved for metadata that the controller uses to keep track of the array. This metadata is inaccessible to the host. Disks made transportable (using the TRANSPORTABLE switch of the ADD DISKS command) do not contain metadata. The default chunk size for storagesets with less than or equal to nine members is 256 blocks, or 128 kilobytes (K). The default chunk size for storagesets with more than nine members is 128 blocks or 64K. A LASHING LED helps to distinguish between located devices and failed devices.NOTE: This command is used only on disks already configured as units or members of a stripeset. Use the ADD MIRRORSETS command to create a mirrorset from disk drives not already members of higher-level containers. Syntax POWEROFF Parameters There are no parameters for this command.When using the REDUCE command to take a snapshot of a striped mirrorset, you must reduce all mirrorsets with one command. A normal member is a mirrorset member whose entire contents are the same as all other normal members within the mirrorset. NOTE: An error is displayed if you attempt to reduce any mirrorset so that there would not be any normal member remaining. NOTE: Units, remote copy sets, and association sets cannot be renamed.Syntax RESTART controller Parameters controller Identifies which controller is to receive the RESTART command.No data is lost if the retry fails.

If a container fails in a way that prevents the data in write-back cache to be written to the container, an unwriteable data error is reported. It then restarts the controller in looping self-test mode. Syntax SELFTEST controller Parameters. NOTE: This command works only in a DRM environment and requires an HSG80 array controller with ACS version 8.7P code. Like all DRM commands, use of this command is heavily restricted. If one member of the association set becomes failsafe locked, any association set member that has failsafe lock enabled also becomes failsafe locked. NOTE: The maximum size of a concatset is 1.024TB CAUTION: This command should be done only with host operating systems that can support dynamic volume expansion. The Maximum Table Length Is Each path between a Fibre Channel adapter in a host computer and an active host port on a controller is a connection. This command adds the specified host connection to the table of known connections. This table is maintained in the controller’s memory. This is the number by which the unit is known internally to the controllers.The allocation class value allows the host to identify the controllers that are a matched dual-redundant pair. This number should be unique for every pair of dual-redundant controllers in the cluster. NOTE: The ADD CONNECTIONS command is not affected by the state of the lock.The controller automatically restarts when this switch is specified.When the replacement controller is installed, the in-place controller tells the node ID to the replacement controller, and the replacement controller automatically assumes the correct port IDs. The range of addresses allowed is 0-EF (hexadecimal). The node-name can be up to eight characters long. It is suggested that the node-name be something meaningful in the context of the DRM setup, such as the location, that distinguishes one controller pair from another. When changed, the new setting for this switch takes effect immediately.

Syntax SET device-name Parameter device-name Specifies the name of the device to change, such as disk or passthrough device.In subsystems with more than one BA370 enclosure, and therefore more than one EMU, the SET EMU command controls both the master and slave EMU settings. The EMU within the primary (master) enclosure instructs the EMUs within the other enclosures to operate at the same settings as the master EMU. The EMU instructs the fans to operate at high speed when any of the temperature setpoints are exceeded or when one or more fans are not functioning. A Manager is a host connection that is allowed to issue CLI commands through a LUN. By default all host connections are enabled as managers. A Manager is a host connection that is allowed to issue CLI commands through a LUN. By default all host connections are enabled as managers. Syntax SET FAILEDSET Parameters There are no parameters associated with this command. Switches AUTOSPARE NOAUTOSPARE Specifies the policy to be used by the controller when a disk drive is physically replaced in the failedset. SET DISK10000 TRANSPORTABLE. 3. Initialize the disk. INITIALIZE DISK10000 4. Delete the disk. DELETE DISK10000 5. Add disk to the Spareset or remove disk from the enclosure. Example To enable the automatic spare feature, enter: SET FAILEDSET AUTOSPARE To disable the automatic spare feature, enter: SET FAILEDSET NOAUTOSPARE. This command allows both controllers to access the storage devices, providing controller fault-tolerant data processing. If one of the two controllers fail, the devices and any cache attached to the failed controller become available to and accessible through the other controller. Syntax SET mirrorset-name Parameter mirrorset-name Specifies the name of the mirrorset to modify. This is the same name given to the mirrorset when it was created with the ADD MIRRORSETS command.

If the member fails out of the mirrorset, the controller selects the first normal member it finds to satisfy its read requests. If these conditions are met, the disk drive specified by disk-name is added to the mirrorset specified by mirrorset-name. Failover is a process that allows a controller to take over total control of the storage subsystem in the event of the failure of its companion controller. IMPORTANT: Remove all connections that appear using the SHOW CONNECTIONS command prior to establishing multibus failover mode. Either command can be used to cancel failover, as they both perform exactly the same actions. For example, cache data will not failover if the operating controller has a failed cache battery because of the risk of data loss if the power is interrupted. NOTE: The number and type of disk drives that are used to create the storageset determine the maximum size of the RAIDset. Syntax SET RAIDset-name Parameters RAIDset-name Specifies the name of the RAIDset to modify. This is the name used with the ADD UNITS command to identify the RAIDset as a host-addressable unit. An error is displayed and the command is rejected if the RAIDset is not in a reduced state, if a replacement policy is already specified, or if the disk specified is already being used by a configuration (including a spareset). NOTE: This command works only in a DRM environment and requires an HSG80 array controller with ACS version 8.7P code. Like all DRM commands, use of this command is heavily restricted. Target-unit-name is the name of the unit to be added to the remote copy set.Syntax SET unit-number Parameters unit-number Specifies the logical unit number to modify. The unit-number is the name given to the unit when it was created using the ADD UNITS command.It can be a single specific host ID, multiple host IDs, or all host IDs (ALL). The default condition is that access paths to all host connections are enabled.

However, under certain conditions, such as when performing a backup, read caching may not be necessary because the data will probably not be re-read. In such instances, it may be beneficial to disable the read cache function and remove the processing overhead associated with caching data. During the restart, the additional memory structures required for Host Based Logging are allocated and initialized. However, the controller may still write to a write-protected RAIDset to satisfy a reconstruct pass or to reconstruct a newly replaced member. Additionally, metadata, reconstruct, and copy writes are still allowed to RAIDsets and mirrorsets.

Syntax SHUTDOWN controller Parameter. NOTE: This command works only in a DRM environment and requires an HSG80 array controller with ACS version 8.7P code. Use of this command is heavily restricted. Refer to the StorageWorks by Compaq Data Replication Manager HSG80 ACS Version 8.7P Operations Guide for an explanation and examples of usage. This command can only be used on mirrorsets already members of higher-level containers (stripesets or units). The UNMIRROR command is not valid for disk drives having a capacity greater than the capacity of the existing mirrorset. Members of an association set transition to the same state simultaneously. For example, if one association set member assumes the failsafe locked condition, then other members of the association set also assume the failsafe locked condition.

SWCC and OpenView Management Appliance Limitations The HSG80 controller does not distinguish be tween commands issued from in-band command tools (SWCC, Command Scripter, or the HP OpenView Storage Management Appliance) and commands issued out of band through the se rial port. Serial port commands should be performed only when the customer has restricted commanding from other sources. Special care must be taken with the Storage Management Appliance (SMA), as it periodically issues polling commands that can interrupt serial port communications. If you w ill be using the serial port on the HSG80 controller, remove the SMA fro m the fabric or use switch zoning to isolate the SMA from the array in which controller s are commanded through a serial port. Using Switch Zoning to Prevent Crashes When Using VTDPY Host Display The HSG80 controller may crash when using th e Display Host functionality in VTDPY. If more than 21 connections are displayed (the equivalent of one page), the controller will crash with a last fail code of 01932588 (cache data a llocation parity error). HP recommends that you use switch zoning to limit the number of connec tions visible to the controller. For more information about switch zoning, refer to the HP StorageWorks Data Replication Manager HSG80 ACS Version 8.7P Configuration Guide.
