Shalom,

There is no way to tell based on the information provided.

vgdisplay -v vg00

Same thing for other volume groups.

follow up with pvdisplay -v on all physical disks.

In light of your additional information there is no way to see mirror configuration from the operating system perspective.

At the console

reboot

F8 when prompted to configure the P400 smart start configuration.

There are menus in there to display mirror configuration.

This is a IA Server.

Please provide following:

vgdisplay -v vg00

lvdisplay -v /dev/vg00/lvol3 |tail -5

cat /stand/bootconf

As told earlier, only through console you can go n check IR..

Hi

use the below commands to check the mirroring status.

vgdisplay -v vg00
lvdisplay -v /dev/vg00/lovl3

This is a IA server so it can have a SAS raid controller and this can be RAID1, so OS can see only one disk.

This is a hardware RAID:

disk 5 0/4/1/0.0.0.4.0 sdisk CLAIMED DEVICE HP IR Volume
/dev/dsk/c4t4d0 /dev/rdsk/c4t4d0

IR = Integrated RAID (1)

You are using an integrated SAS controller.

Try to locate any "sasd_" device and run this to get more info:

# sasmgr get_info -D /dev/sasd0 -q raid
