If these LUNs are from the one SAN, are you trying to mirror data from elsewhere onto the SAN or to mirror SAN LUNs one to another? The latter, for a single SAN, is counter-productive as the SAN is supposed to provide that reliability for you. If the former, then note which device is which LUN (cXtYd0s2 presumably) and then use vxdiskadm to mirror the volumes on a disk. OR if you want to do this one by one, and maybe you don't want all the volumes on a disk mirrored onto this LUN, then build a plex from the bottom up (make the subdisk and then a plex then associate the former with the latter) and then attach it to the volume. Vxassist will be of help. RTFM, the storage admin guide is really helpful and has recipes for doing all these things.

I am looking to mirror it now. The storage person has allocated me another disk of the same size . I intend to make a subdisk and plex and then attach it to the existing volume . Will this activity serve my purpose ? Please advise . The command I used to create the volume - vxassist -g <dg> make <volname> 30g <disk> Regards, Ajay ***** The information transmitted is intended only for the person or entity to which it is addressed and may contain confidential, proprietary, and/or privileged material.
