Creating A Flashcopy Logical Drive By Specifying A Number Of Disk Drives - IBM System Storage DS3000 Programming Manual

create FlashCopyLogicalDrive baseLogicalDrive="baseLogicalDriveName"
[repositorysubsystem=subsystemNumber
freeCapacityArea=freeCapacityIndexNumber
userLabel="FlashCopyLogicalDriveName"
warningThresholdPercent=percentValue
repositoryPercentOfBase=percentValue
repositoryUserLabel=repositoryName
repositoryFullPolicy=(failBaseWrites | failFlashCopy)]
[enclosureLossProtect=(TRUE | FALSE)]
This example shows a command in which the storage management software assigns the disk drives:
c:\...\...\client>smcli 123.45.67.89 -c "create
FlashCopyLogicalDrive baseLogicalDrive=\"Mars_Spirit_4\"
repositorysubsystem=2 freeCapacityArea=2;"
The command in this example creates a new FlashCopy repository logical drive in subsystem 2. The base
logical drive is Mars_Spirit_4. The size of the FlashCopy repository logical drive is 4 GB. This command
also takes a FlashCopy of the base logical drive, starting the copy-on-write operation.
When you define the capacity of a FlashCopy repository logical drive, specify a size that is 20 percent of
the size of the base logical drive. In the previous example, the size of the FlashCopy repository logical
drive is set to 4 GB. The underlying assumption is that the base logical drive size is 20 GB (0.2 x 20 GB=
4 GB).
This example shows how to use the command in a script file:
create FlashCopyLogicalDrive baseLogicalDrive="Mars_Spirit_4"
repositorysubsystem=2 freeCapacityArea=2;
Creating a FlashCopy Logical Drive by Specifying a Number of Disk
Drives
With this version of the create flashcopyLogicalDrive command, you must specify the number of disk
drives and the RAID level that you want for the FlashCopy repository logical drive. This version of the
create flashcopyLogicalDrive command creates a new subsystem. You must have disk drives in the
storage subsystem that are not assigned to an subsystem for this command to work.
create flashcopyLogicalDrive baseLogicaldrive="baseLogicalDriveName"
[repositoryRAIDLevel=(1 | 3 | 5 | 6)
repositoryDriveCount=numberOfDrives
driveType=(fibre | SATA | SAS)
userLabel="flashcopyLogicalDriveName"
warningThresholdPercent=percentValue
repositoryPercentOfBase=percentValue
repositoryUserLabel="repositoryName"
repositoryFullPolicy=(failBaseWrites | failFlashCopy)]
[enclosureLossProtect=(TRUE | FALSE)]
This example shows how to use a command in which users specify the number of disk drives:
c:\...\...\client>smcli 123.45.67.89 -c "create flashcopyLogicalDrive baseLogicalDrive=\
"Mars_Spirit_4\" repositoryRAIDLevel=5 repositoryDriveCount=3;"
The command in this example creates a new FlashCopy repository logical drive that consists of three disk
drives. Three disk drives comprise a new subsystem that has a RAID level of 5. This command also takes
a FlashCopy of the base logical drive, which starts the copy-on-write operation.
This example shows how to use the command in a script file:
create flashcopyLogicalDrive baseLogicalDrive= "Mars_Spirit_4"
repositoryRAIDLevel=5 repositoryDriveCount=3;
