looking for "business copy" commands which is equivalent to EMC bcv commands

[Hanry Zhou]

I posted this message over SAN section, but have not heard any response, so trying it again here. Hope you don't mind.

I used to work on EMC bcv commands, for instance, "symmir" command, it allows you to make sync, and split. On HP "Business Copy" product which is similar to bcv, what are these equivalent commands, and is SSSU is the tool that I have to install, in order to use these commands?

Thanks!

Not sure what symmir does but the standard sssu command you'd use to make a snapshot of a lun and present it to another host would be.

ADD SNAPSHOT copydisk1 VDISK="\Virtual Disks\server01\Disk1\ACTIVE" ALLOCATION_POLICY=DEMAND REDUNDANCY=VRAID5

ADD LUN 1 VDISK="\Virtual Disks\Server01\disk1\copydisk1" HOST=server2

Hope this helps

Hanry,

I think you are talking about mirroring within an array and mirroring across array's.

Business Copy is XP mirroring within the array, and Continous Access across arrays.

Both of these tools require RaidManager to be installed on the host.

This doc should help point you in the right direction.

You didn't mention the type of array you were using. (EVA or XP) I'm assuming you are referring to an EVA based on the SSSU option.

Pre- firmware 6.0, the EVA didn't support mirrors the same way the EMC does. The Business copy was a point in time snapshot of a LUN not a Mirror of a LUN that could be fractured and re-synced.

With firmware 6.0 the EVA added the mirror capability to the eva in addition to the snapshot and snapclone features.

CommandView is really the software that instructs the EVA to make mirrors and snapshots and to fracture and resync the mirrors. This is a web based GUI tool. SSSU provides a command based access to commandView that allows commandview commands to be scripted.

I suggest you start with the GUI until you get a feel for what you want to do. You can create mirrors, fracture them and resync them. Once you have the exact sequence down, you can then script it with SSSU.
