Field Storage pool Reported size Snapshot reserve RAID preference Load balancing Access type Shared access Sector size Table 548. Space Field Volume Status Storage pool Reported size Volume reserve Free space Snapshot reserve Description Storage pool where the volume is located Reported size of the volume in MB, GB, or TB. The group rounds up volume sizes to the next 15MB if the size is not a multiple of 15MB. You cannot change the reported size of a template volume. Indicates the amount of snapshot reserve for each volume as a percentage of the volume reserve RAID configuration for the volume; automatic indicates that the RAID configuration is the same as that of the pool containing the volume. The RAID preference can have one of the following statuses: • Honored - The requested RAID preference has been applied to the volume. • In-Progress - The volume is being converted to the requested RAID preference. • Oversubscribed - The size of the volume exceeds the available space of any group members running the preferred RAID level. The requested RAID preference has not been applied to the volume. • Not available - No group members are running the preferred RAID level; the requested RAID preference has not been applied to the volume. • Temporarily Unknown - An internal operation is in progress and the RAID status cannot be determined. After the operation is completed, the status is displayed. Indicates whether load balancing is enabled Read-write or read-only. A volume can have read-only or read-write permission, unless it is a template volume, which must be read-only. Shared (multihost access) or not shared Either 512 bytes or 4K bytes. The logical sector size assigned to a volume does not depend on the sector size used by the physical drives on the array. For example, a volume can use 4K-byte logical sectors even if the physical drives on the array use 512-byte sectors. Description Name of the volume Indicates whether a volume is online or offline. An iSCSI initiator can only discover or connect to an online volume. Storage pool where the volume is located Reported size of the volume in MB, GB, or TB. The group rounds up volume sizes to the next 15MB if the size is not a multiple of 15MB. You cannot change the reported size of a template volume. Actual amount of pool space that the group allocates to a volume. The value of the volume reserve depends on whether you enable thin provisioning on a volume: • If thin provisioning is disabled, volume reserve is equal to the reported size. • If thin provisioning is enabled, volume reserve is equal to or less than the reported size, depending on volume usage and the thin-provisioning settings. Unused space on the volume Amount of space, based on a percentage of the volume reserve, that the group allocates to snapshots Reference: GUI Panels, Wizards, and Dialog Boxes 581
