rx6600 How to find out if hardware mirored

[Basheer_2]

Hello itrc,

rx6600 integrity
11.31
has 3 internal Disks

I want to know if the OS is mirrored ( lvlnboot -v shows only one disk.
so it is not software mirrored)

Any commands to find out if hardware mirroring is done on this.

Hi Basheer,

To find out the OS mirroring try this command

lvdisplay /dev/vg00/lvol1 and look for "Mirror copies " , if you find any non zero value means it is mirrored.( check this for all lvs in the vg00 .. or atleast lvol1 to 3)

Regards!

Oops ..missed about hardware mirroring ..

I hope rx6600 comes with SAS controller..
try this

1) find out the SAS controller
# ioscan -fun |grep -i sas

2) to find out tyhe raid configuration

#sasmgr get_info -D -q raid

eg : sasmgr get_info -D /dev/sasd0 -q raid


rgds!

It seems disks in enclosure 1 on bay 7 and 8 is mirrored and disks in bay 5 and 6 is not part of array - may be presented as normal disks
