Dell PowerVault MD3260i - Manual (Page 59)

To remove CGGroup_1, as well as all repository virtual disks:
set consistencyGroup ["CGGroup_1"] removeCGMemberVirtualDisk=" payroll_backup"
deleteRepositoryMembers=TRUE;
Or omit the deleteRepositoryMembers parameter, which invokes the default value of preserving repository
virtual disks:
set consistencyGroup ["CGGroup_1"] removeCGMemberVirtualDisk=" payroll_backup";
Changing The Pre-read Consistency Check Setting Of An Overall Repository Virtual Disk
Use the Pre-Read Consistency Check option to define a storage array's capability to pre-read an overall repository
virtual disk consistency information and determine whether the data of that overall repository virtual disk is consistent.
An overall repository virtual disk that has this feature enabled returns read errors if the data is determined to be
inconsistent by the RAID controller module firmware.
You can enable this option for overall repository virtual disks that contain consistency information. RAID Level 1, RAID
Level 5, and RAID Level 6 maintain redundancy information.
You can change the Pre-Read Consistency Check for an overall repository for the following storage objects:
• Snapshot group
• Snapshot virtual disk
• Consistency group member virtual disk
• Replicated Pair
This command defines the properties for a virtual disk. You can use most parameters to define properties for one or
more virtual disks. You can also use some parameters to define properties for only one virtual disk. The syntax
definitions are separated to show which parameters apply to several virtual disks and which apply to only one virtual
disk.
NOTE: In configurations where disk groups consist of more than 32 virtual disks, the operation can result in host I/O
errors or internal RAID controller module reboots due to the expiration of the timeout period before the operation
completes. If you experience host I/O errors or internal RAID controller module reboots, quiesce the host I/O and
try the operation again.
