Parameter preReadRedundancyCheck accessVirtualDisk logicalUnitNumber host hostGroup Description The setting to check the consistency of RAID redundancy data on the stripes during read operations. Do not use this operation for nonredundant virtual disks, for example RAID Level 0. To check redundancy consistency, set this parameter to TRUE. For no stripe checking, set this parameter to FALSE. Specifies the logical unit number for the access virtual disk. The logical unit number is the only property that you can set for the access virtual disk. NOTE: If you specify the accessVirtualDisk parameter, the only property that you can set is the logicalUnitNumber. Defines specific virtual disk-to-LUN mappings to an individual host or assigns the host to a host group. Specifies the name of the host to which the virtual disk is mapped. You must put quotation marks (" ") around the host name. Specifies the name of the host group to which the virtual disk is mapped. You must put quotation marks (" ") around the host group name. NOTE: When using this command, you can specify one or more of the parameters. You do not, however, need to use all of the parameters. NOTE: You can apply the addCapacity, segmentSize, userLabel, and logicalUnitNumber parameters to only one virtual disk at a time. NOTE: Setting the addCapacity, addPhysicalDisks, or segmentSize parameter starts a long-running operation that you cannot stop. These long-running operations are performed in the background and do not prevent you from running other commands. To display the progress of long-running operations, use the show virtualDisk actionProgress command. 222 Script Commands
