and the mirror disks are on channel 2. However, specifying disks in the order 1:2,
2:2, 1:3, and 2:3 would result in mirrored pairs of 1:2/1:3 and 2:2/2:3. This
would put the data disk and mirror disk of each pair in the same enclosure, making
the LUN vulnerable to an enclosure failure.
-D LUN Delete the LUN identified by LUN.
-force Allows a LUN to be created using two or more disks in the same enclosure. This
option allows you to override the high-availability protection designed into the LUN
binding process. Using this option you can specify more than one disk per enclosure.
You can also use this option to create a RAID 5 LUN that includes more than six
disks.
-L cntrlrID:LUN
Create a LUN with the number specified by LUN. The LUN will be owned by the con-
troller identified by cntrlrID.
-M LUN -c cntrlrID
Change the ownership of the LUN specified by LUN to the controller specified by
cntrlrID.
-r RAIDlevel Identifies the RAID level used for the LUN. RAID levels that can be specified are 1
and 5. A RAID 0/1 LUN is created by selecting RAID 1 with more than two disks.
-R cntrlrID:LUN
Replace (unbind and rebind) the LUN with the number specified by LUN on the con-
troller identified by cntrlrID.
-s SegmentSize
Identifies the stripe segment size used for the LUN. The stripe segment size is
specified in Kbytes and must be a multiple of the current cache page size setting. For
example, if the cache page size is set to 4 Kbytes, valid settings would be 4, 8, 16, 64,
etc.
-V Verbose mode displays additionalcommand execution, state, and/or status messages.
-? Display expanded usage message. This option overrides all others.
