Mirroring of non-mirrored Disks in MA8000 Storage

[Vimal Upreti <Vimal@xxxxxxxxxxxx>]

Dear all,
I have a query related to MA8000 (HSG80) controller. Presently there is
a TruCluster 5.1A running on 2*Alphaserver ES40 with one MA8000 Storage.
The configuration of Cluster OS Disks in MA8000 Storage is as follows:
Member1 Disk : 1* 9GB (Un-mirrored)
Member2 Disk : 1* 9GB (Un-mirrored)
Quorum Disk  : 1* 9GB (Un-mirrored)
Cluster-OS   : 2* 18GB(Mirrored)

Now I'm worried on the Disks which are Un-mirrored (M1, M2, Q & CL-OS)
in MA8000 Storage. Can you please let me know the procedure to Mirror
these un-mirrored 9GB Disks. I have sufficient no. of 9GB spare disks to
mirror.

Since these are Cluster-OS disks with lots of CDSL etc., so I 'm not
comfortable with Tape Backup & restoration.

Thanks in advance.
