BCV restore to alternate STD
Hello Everyone,
I need to restore BCV data to an alternate STD. I have done this before using the symmir -sid sid id -f filename.txt restore -full and it works fine.
My question is that after the full restores were complete to the alternate STD and were split, I then needed the BCV's to be associated back with their original STD's again. With my limited experience, I went back and ran a full establish to the original STD's which worked fine, but was very time consuming.
I have seen the 'associate' command (never used it) and was wondering if this would work instead? Could I somehow reassociate the BCV back to it's original STD and then on next establish, it would just perform it's normal incremental establish?
Thanks in advance!!

Sorry, but I think I'm looking for a single BCV to multiple STDs (?)
I believe after I split the BCV from the second STD, the normal establish back to the original STD did not work and I had to perform a -full.Darrell-uVlTI

Agreed. So, do I have to perform a -full to the original STD or can I somehow re-associate them in a different way so I don't have to perform the full to get the relationship re-created?

Darrell- actually ..i am wrong ..this is what TimeFinder doc says:
Establishing multiple BCVs with a single standard device You can fully establish (at different times) up to eight BCV devices associated with a single standard device. The BCV devices must also be associated to the same device group. Note: Using the environment variable SYMCLI_MAX_BCV_PAIRS, the maximum number of pairs (established or restored) can be adjusted between 1 to 16 BCV devices. With this feature, standard devices retain a relationship with multiple BCVs as long as those BCVs do not become paired with another standard. - i am looking at TimeFinder doc and can't find anything that says you can do that. STD device can be associated to multiple BCVs, but a BCV can only be associated to one STD. I would try the attach command:
"symmir -g prod attach DEV001 BCV ld BCV001" and then establish it "symmir -g ProdBgrp -full establish DEV001 BCV ld BCV001 -noprompt"
..but i doubt it would work ..worth a shot. Darrell-uVlTI

At that point, you are still performing a full establish, right? (In the second command I see the -full switch)
If that's the only option I have, then that will have to do. After further research, the 'associate' option I was mentioning was for symbcv which isn't what is needed here....
How about running a normal establish with the -force option?- thats a pretty good suggestion..you could clone from bcv to another standard device ..the only caviat i see is that your BCV can not be raid-5 ..it has to be either unprotected bcv or 2 way mirrir bcv and it has to be in split state before you initiate symclone session. I would also find out what state your clone session needs to be before you re-establish your bcv.
