disk Commands The Rev Column The Rev column displays the revision number of the SCSI device. The Block Column The Block column displays the number of blocks available on the SCSI device. The Bytes/Block Column The Bytes/Block column displays the number of bytes for each block on the SCSI device. The Usage Column The Usage column displays the usage of the SCSI device. The disk list command can display one of the values listed in Table 5-2. Table 5-2 SCSI Disk Device Usage Values Value Detached DOS Initialized Not Initialized Offline Unowned Meaning The system detected that the diskset in the detached state. When a diskset is detached, it is not available for use. The SCSI device was prepared for use (initialized) with MS-DOS partitions. The SCSI device was prepared for use (initialized) with arrays. The SCSI device was not prepared for use (initialized) with arrays. The SCSI device was present at boot time. However, the device is either removed from the controller or it failed. The controller does not own the SCSI device. The Shared Column The Shared column displays the value YES if the device resides on a shared channel and the value NO if the device does not reside on a shared channel.
