Disc mirroring

[William Bourne]

How can I tell if I have disc mirroring software installed on my RX4640 run HPUX 11i v2

[Pete Randall]

root# swlist |grep -i mirror
B2491BA B.11.11 MirrorDisk/UX

It may also depend on the O/S loaded.

With the newer versions MirrorDisk and OnlineJFS is bundled with certain O/S pkgs.
A base OE doesn't include them...but I believe the Enterprise OE or MissionCritical OE includes them....and you might not see this if you run swlist and grep for mirror.

So check which version of O/S you got with swlist...base/Enterprise/MissionCritical..

Try:

vxlicense -p

Hi William,

Even if Mirror-UX was bundled in the OE, the following will find it:

swlist -l fileset | grep -i mirror

Hey Thanks Jeff...forgot about using the fileset option to find it.

MirrorDisk/UX is the name of mirroring software on HPUX so command to search is
# swlist |grep -i mirror
If it return result as
# swlist |grep -i mirror
B2491BA B.11.11 MirrorDisk/UX
It means this software is installed

If you are running HP-UX Enterprise OE, you already have Mirrordisk/UX.

swlist -l fileset}grep mirror

If not and MirrorDisk was added:

swlist|grep -i mirror


One thing that I am 100% sure though is regardless of OE release (Foundation or Enterprise) - you got FREE mirroring with VxVM which is bundled with the OS. Note though that the mirroring will only work on the OS disks IF you use VxVM to manage/encapsulate your OS. To mirror the rest - you need FUll VxVM or MirrorDisk/UX if you manage the rerst of your storage with LVM.

Hoipe this helps.
