Do I need to mirror all disk devices?Answer:
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.Question:
Can I use one volume manager for the local disks (boot disk) and a different volume manager for the multihost disks?Answer:
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.
