Guidelines for Disk Sets

• The default total number of disk sets on a system is 4. You can increase this value up to 32 by editing the /kernel/drv/md.conf file, as described in How to Increase the Number of Default Disk Sets. The number of shared disk sets is always one less than the md_nsets value, because the local set is included in md_nsets.

• Unlike local volume administration, it is not necessary to create or delete state database replicas manually on the disk set. Solaris Volume Manager tries to balance a reasonable number of replicas across all drives in a disk set.

• When drives are added to a disk set, Solaris Volume Manager re-balances the state database replicas across the remaining drives. Later, if necessary, you can change the replica layout with the metadb command.
