need a solution for SRL volume in VVR

Created: 05 Mar 2013 • Updated: 10 Mar 2013 | 3 comments
This issue has been solved. See solution.

 

we have VCS Global cluster  and replication by VVR.

SRL volume looks like as below. I need to correct it.

I need to remove plex %63 and then relocate subdisk of plex oss_srl_vol-02 to other disk.

Can I remove and add plexes to SRL volume online ?

You can add plexes online to ANY volume so this include SRL volumes and you remove plexes online (as long as there is one remaining good plex, of course!)

Do we need to stop replication before running plex dissociation and mirroring command?

ofcourse one plex ( oss_srl_vol-01) as shown above   will always be healthy and available

we will be working on other two plexes

No this can be done online with replication running.
