Easy points. Am I safe? Are my boot disks mirrored?

On my RX6600 I am trying to be certain I have my boot disks mirrored properly. On most of the boxes I have smartarray controllers and can see status using sautil, but on a few I have MPT controllers and I only see a single disk and don't see a way to see inside the "array" (presuming that's really what it is).

How do I confirm (short of yanking a disk) that my disks are mirrored properly?

Here's output from my ioscan:
ba 6 0/4 lba CLAIMED BUS_NEXUS Local PCI-X Bus Adapter (122e)
slot 4 0/4/1 pci_slot CLAIMED SLOT PCI Slot
escsi_ctlr 1 0/4/1/0 sasd CLAIMED INTERFACE HP PCI/PCI-X SAS MPT Adapter
/dev/sasd1
ext_bus 0 0/4/1/0.0.0 sasd_vbus CLAIMED INTERFACE SAS Device Interface
target 26 0/4/1/0.0.0.0 tgt CLAIMED DEVICE
disk 0 0/4/1/0.0.0.0.0 sdisk CLAIMED DEVICE HP IR Volume
/dev/dsk/c0t0d0 /dev/dsk/c0t0d0s2 /dev/rdsk/c0t0d0 /dev/rdsk/c0t0d0s2
/dev/dsk/c0t0d0s1 /dev/dsk/c0t0d0s3 /dev/rdsk/c0t0d0s1 /dev/rdsk/c0t0d0s3


There are actually a couple of drives inside the volume -- how do I verify that they're mirrored?

Do:

sasmgr -N get_info -D /dev/sasd1 -q raid

Re: Easy points. Am I safe? Are my boot disks mirrored?

also do on sasd0 if you have one.

If your OS boot disk is on a PV that says IR Volume -- that means it is on that SAS RAID controller.

do a : diskinfo /dev/rdsk/disnNN

where diskNN is the PV returned by vgdisplay -v vg00 (or whatever vgNN your Boot disk is LVM'd on).

You see the command above and if you see

HP IR Volume

it is an Integrated RAID, a mirror done by hardware.

Hope this helps!
