We have Proliant DL380 G2 running Solaris 9 x86
There are 6 physical disks installed which I believe are mirrored at hardware level to 3 sets to present 3 disks to the OS.
Is there any way to check the mirror status at OS level ?
I am guessing not and it may need a trip to site as we have no ilom access remotely but hoping someone has a different answer
