scripts that mirror/clone an existing lun
Anyone has scripts that clone an existing lun? Our DBAs are constantly cloning Oracle databases that span multiple luns. I've read some of the forum posting and understand that Replication Manager might be a better product to use. However, I was also told that Replication Manager currently is not supported under Linux for Itanium 64 bit (we are using HP Integrity Itanium server running Linux AS 4 Update 5). So looks like we cannot use Replication Manager and have to roll our own scripts.
I'm looking for something as a starting point. It does not have to be fancy and we are going to manually ask the DBA to either shutdown Oracle prior to fracturing the clone.
BTW, I tried to do this by hand last week for the first time (cloning a few luns). Selecting the destination lun for cloning takes a long time - typically at least 2 or 3 minutes. Is this normal or am I doing something wrong? This is part of the reason we are looking to automate through scripting.
Cheers,
Derek

yeah ..doing cloning through Navisphere is ssoooo slow
to create a clone group and add lun 5 as our clone source
to add target lun 7 and begin clone process
once state of clones changes to synchronized, put Oracle in hot backup mode, make sure state is still synchronized and issue fracture
take Oracle out of hot backup mode.
you can configure password file so you don't have to have passwords in your scripts.
check out document called "EMC SnapView Command line interfaces"
