show snap-pools Description Shows information about snap pools owned by a specified controller or both controllers. NOTE: The process of freeing space associated with deleted snapshots occurs more slowly when the system is operating write-through cache mode than in write-back cache mode. Therefore, there will be a delay between deleting the snapshots and when their used space is shown as free space by the show snap-pools command. Syntax show snap-pools [controller a|b|both] Parameters controller a|b|both Optional. Shows snap pools owned by controller A only, by controller B only, or by either controller (both). If this parameter is omitted, all snap pools owned by either controller are shown. Output Vdisk Vdisk name Serial Number Snap pool serial number Name Snap pool name Size Total size of the snap pool volume Free (size) Amount of free space available in this snap pool Master Volumes Number of master volumes associated with this snap pool Snapshots Number of snapshots using this snap pool Status • Available: The snap pool is available for use. • Offline: The snap pool is not available for use, as in the case where its disks are not present. • Corrupt: The snap pool's data integrity has been compromised; the snap pool can no longer be used. Threshold Snap pool threshold level: • Warning: The snap pool is moderately full. When this threshold is reached, an event is generated to alert the administrator. The default is 75%. • Error: The snap pool is nearly full and unless corrective action is taken, snapshot data loss is probable. When this threshold is reached, an event is generated to alert the administrator and the associated snap-pool policy is triggered. The default is 90%. • Critical: The snap pool is 98% full and data loss is imminent. When this threshold is reached, an event is generated to alert the administrator and the associated snap-pool policy is triggered. %Usage Threshold value (percent of snap pool space used) that triggers the threshold's policy show snap-pools 291
