Can symmir restore command not restored the data if the target std device

Question

My Scenario was .........

1. Production STD device -------------EST............New BCV TGT device
2, NEW BCV TGT device --------------restore-------------New STD device

As per procedure first i have to bring the database in hotbackup mode and then est and split...

but i have executed restore command instead of est for 1 st step and top of it mount point were up on production and whole restored operation completed and then later i realized that i have done mistake.... but surprisingly the data is intact on production Std device which i think it shouldn't. I don't how ?

IS it means the restore opertaion not replicate data from BCV to std as the mount point was up and running on production at that time

is it any chance if i unmount and then mount the file system......i will loss the data on production.

hmmm......seems like u should loose the data........have u tried vgexport...import on the host........

i think there is no alternative as after restore command all the tracks updated on production volume..........i think before u execute split .......there must be some way to rollback the changes.

tks, welcome to the forums. When you get the chance be sure to introduce yourself in the coffee break area.

What was the time from from when you split the BCV to when you executed the restore back to the production standard?

Mike,Its BCV was not configured earlier what i have to do is to presnet the same data to other STD device so i have to est the bcv first and once the data come to bcv disk then to restore to new STD disk.............but i did not replicate the data from production to the BCV device instead i executed restore command from newly created BCV disk to existing production disk.......so it means there should be no data remains on production after restore but the data is intact ands the command was executed error free

tks,You will not be able to do a restore operation if the BCV is never established.! Please check the symapi logs under /var/symapi/log -Raju

I'm not 100% sure .. But I think you can fully restore a BCV to whatever volume. Regardless of its SDDF relation.Message was edited by: Stefano Del Corno

It seems not.. I just given a try!

symmir -sid XXX -g test_bvc restore -full

Execute 'Full Restore' operation for device group
'test_bvc' (y/ ) ? y

'Full Restore' operation execution is in progress for
device group 'test_bvc'. Please wait...

Cannot proceed when the BCV state is 'Split No Incremental' except if the force flag or exact pairing is used

symmir -sid XXX -g test_bvc restore -full -force

Execute 'Full Restore' operation for device group
'test_bvc' (y/ ) ? y

'Full Restore' operation execution is in progress for
device group 'test_bvc'. Please wait...

Cannot proceed because the device does not have any BCV pairing relationship
