Command Line Interface Reference Guide
Note: Use this switch for a single-controller configuration only. HP does not
recommend using this switch for controllers in a dual-redundant configuration.
Note: If any storageset within the configuration was previously initialized with the
INITIALIZE container-name SAVE_CONFIGURATION command to save
the configuration to disk, it is not necessary to reconfigure devices with a new
controller.
Also, some devices within containers that were initialized with the
SAVE_CONFIGURATION switch in earlier versions of ACS firmware (V8.5 through
V8.6-9), may no longer display a status as a configuration saving device. You can
validate the save configuration usage by issuing the SHOW DEVICE_INFO
FMU
command. Refer to the
HP StorageWorks HSG60 and HSG80 Array Controller and
Array Controller Software Troubleshooting Guide
for additional information under the
SHOW DEVICE_INFO
FMU command.
Note: ACS saves any installed software patches on disks initialized with the
SAVE_CONFIGURATION command. To replace a controller and restore the
configuration from a disk, you do not have to reinstall any software patches.
Note: If you enable the SAVE_CONFIGURATION switch by issuing INITIALIZE
diskxyyzz SAVE_CONFIGURATION command for a JBOD disk, the
configuration is not saved to the device until the unit is placed above the device. A unit
is placed above the device after issuing the ADD UNITS
dx diskxyyzz. After
issuing the SHOW DEVICES
FULL command, the subsequent screen display does not
show the configuration saved to the disk until it has a unit above it as well. To utilize a
single JBOD disk as a
SAVE_CONFIGURATION device, you must initialize the
device with
SAVE_CONFIGURATION and place a unit on top of it. The unit does
not have to be enabled to any host.
If you enable a container with
SAVE_CONFIGURATION switch, the member
devices are used for save configuration operation, and after you issue the SHOW
DEVICES
FULL command, the subsequent screen display indicates that the member
devices are utilized for save configuration operations.
The SAVE_CONFIGURATION switch requires only one disk to be
initialized with this option. However, more disks can be used, if desired, for
redundancy.
