is allowed to resync the disk drives, the data on the primary disk drive
will be available when you access the newly created volume.
The following rules must be observed when creating IM, IME, and IS
volumes and hot spare disks:
1. All disks that are part of a volume, including hot spares for that
volume, must be on the same SAS controller or on the same SCSI
bus (for SCSI controllers).
2. IM, IME, and IS volumes are supported.
3. A maximum of two IM, IME, or IS volumes per controller can be
created.
4. The total number of disks in a volume, including hot spare disks,
cannot exceed six for LSI53C1020/1030 controllers.
5. The total number of disks in a volume, including hot spare disks,
cannot exceed eight for SAS1064/1064E and SAS1068/1068E
controllers, and the total number of disks combined for two volumes
cannot exceed ten. (Ten disks is a theoretical upper limit for the
firmware; the SAS controller may actually support a lesser number
of disks.)
6. An IM volume must have exactly two disks.
7. An IME volume can have a minimum of three disks and a maximum
of six disks (for LSI53C1020/1030 controllers) or eight disks (for SAS
controllers), as long as rules 4 and 5 are not violated.
Command Line –
