clarification on Mirror

[MKR_1]

HI Admins

Do we really need MirrorDisk package to mirror boot disk.Please clarify.

I see a server which is has mirrored boot disk but didnot have the MirrorDisk package

Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c1t6d0 (0/0/2/0.6.0) -- Boot Disk
/dev/dsk/c2t6d0 (0/0/2/1.6.0) -- Boot Disk



[root]v:/opt> swlist -l product |grep MirrorDisk
[root]v:/opt>

Shalom,

swlist -l product |grep -i mirror

Your original statement does not get you a listing on mirror/ux

Clearly from the output mirror/ux is installed.

Take a look at this post to see how mirroring is done. It has several good check commands.

Hi,

the correct way to check if the Mirror is installed

swlist -l fileset |grep -i mirror

It's now a fileset of LVM, so you could not see it by swlist -l product.

HTH.

Output of swlist

swlist -l fileset | grep -i mirror
LVM.LVM-MIRROR-RUN B.11.11 LVM-MIRROR-RUN
PHCO_34196.LVM-MIRROR-RUN 1.0 LVM.LVM-MIRROR-RUN

Is this the package for mirroring.The os in the server is B.11.11

Hi,

ok, so no doubts, you have the Mirror Disk software on your system.

Hi,

1)Do we really need MirrorDisk package to mirror boot disk.Please clarify.??
==>Yes you required Mirror Unix to mirror.
To check use below command,
#swlist -l bundle|grep -i mirror
or
#swlist -l fileset | grep -i mirror

2)swlist -l fileset | grep -i mirror
LVM.LVM-MIRROR-RUN B.11.11 LVM-MIRROR-RUN
PHCO_34196.LVM-MIRROR-RUN 1.0 LVM.LVM-MIRROR-RUN

Is this the package for mirroring.The os in the server is B.11.11??
==>Yes, it is enabled on your system, you can perform mirroring.
