To add a new base virtual disk to a consistency group and create a new repository virtual disk using a diskpool:set consistencyGroup ["consistencyGroupName"]addCGMemberVolume="baseVirtualDiskName" repositoryVirtualDisk=("diskPoolName"capacity=capacityValue(KB|MB|GB|TB|bytes))Restrictions• The Snapshot premium feature must be enabled on the storage array.• To add a new member virtual disk, the consistency group must fewer than the maximum number ofvirtual disks allowed in your configuration.• If the base virtual disk resides on a standard disk group, the repository members for any associatedconsistency group can reside on either a standard disk group or a disk pool. If a base virtual diskresides on a disk pool, the repository members for any associated consistency group must reside onthe same disk pool as the base virtual disk.• You cannot add a virtual disk to a consistency group that is in a Failed state.Removing A Member Virtual Disk From A Consistency GroupWhen removing a member virtual disk from an existing snapshot consistency group, you can also deletethe repository virtual disk members from the consistency group, if desired.The remove command syntax is shown below:set consistencyGroup ["consistencyGroupName"]removeCGMemberVirtualDisk="memberVirtualDiskName"[deleteRepositoryMembers=(TRUE | FALSE)]The removeCGMemberVirtualDisk parameter is the name of the member virtual disk that you want toremove; deleteRepositoryMembers determines whether the command removes all the repositorymembers from the consistency group.To remove a virtual disk names payroll-backup from a consistency group named CGGroup_1, butpreserve the repository virtual disks:set consistencyGroup ["CGGroup_1"] removeCGMemberVirtualDisk="payroll_backup"deleteRepositoryMembers=FALSE;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 preservingrepository virtual disks:set consistencyGroup ["CGGroup_1"] removeCGMemberVirtualDisk=" payroll_backup";Changing The Pre-read Consistency Check Setting Of An Overall RepositoryVirtual DiskUse the Pre-Read Consistency Check option to define a storage array's capability to pre-read an overallrepository virtual disk consistency information and determine whether the data of that overall repositoryvirtual disk is consistent. An overall repository virtual disk that has this feature enabled returns read errorsif 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. RAIDLevel 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 storageobjects:61
