Creating a DiskSuite RAID5 device
Creating a RAID 5 metadevice with Solstice DiskSuite is extremely simple. Unlike creating mirrors which involves several steps, creating a RAID 5 device consists of running a single command.
metainit <metadevice> -r <disk1> <disk2> <disk3> <disk4> <disk5> -i interleave [-h <hotspare>]
-rsignifies that this will be a RAID 5 device
-ispecifies the interleave size to be used
-hspecifies the hot spare pool
NOTE: If hot spare disks are desired, the hot spare pool must have been previously created before creating the raid 5
The following example creates the hot spare pool
hsp001 and then the
d110 RAID 5 device.
- Create the hotspare spool
# metainit hsp001 c1t2d0s0 c2t2d0s0 c3t2d0s0
- Create the RAID 5 device
# metainit d30 -r c1t1d0s0 c2t0d0s0 c2t1d0s0 c3t0d0s0 c3t1d0s0 -i 64k -h hsp001
