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:
SPARC: 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.
x86: No, this configuration is not supported, as only Solaris Volume Manager is supported in x86 based clusters.
