Mirror boot disk !
Hi All,
Plan to do one mirror for boot disk,
but ioscan found it is IR vloume, but lvlnboot -v only show one disk, and I use command sasmgr to check IR volume found disk /dev/rdsk/c35t0d0,/dev/rdsk/c35t1d0,
if it means they are pair for IR volume?
I post some command for your reference, thanks!

Re: Mirror boot disk !
>> but ioscan found it is IR vloume,
This means "Integrated RAID" - it is already a (hardware) mirror.
Disks are in slot 3/5 and 1/2.
As you can see you already have 2 pairs of mirrored disks, no need to mirror them by LVM.
Hope this helps!
Regards
Torsten.

Re: Mirror boot disk !
Yes. Torsen is absolutely correct.
There is IR Volumes. IR = integrated RAID (mirror), built on the internal SAS controller. shown in sasmgr command.
So there is no need to mirror them again in OS.
