Volume Management FAQs

• Do I need to mirror all disk devices?

  For a disk device to be considered highly available, it must be mirrored, or use RAID-5 hardware. All data services should use either highly available disk devices, or cluster file systems mounted on highly available disk devices. Such configurations can tolerate single disk failures.

• Can I use one volume manager for the local disks (boot disk) and a different volume manager for the multihost disks?

  This configuration is supported with the Solaris Volume Manager software managing the local disks and VERITAS Volume Manager managing the multihost disks. No other combination is supported.
