Mount bcv to mount host using RM 5.1

Question

I already posted this to the RM forum but thought I would post it here as well as most of my questions are related to how the mount of bcvs/clones on a DMX work.

Environment:
DMX-4 5772.83
RM 5.1
Windows Server 2003

I have a job in RM that clones 7 metas to bcvs on a nightly basis. This works fine. I would like to start mounting the bcvs to a development server daily for test and development access. I have done this with Clariions before, but am not as familiar with the process on the DMX.

The dev server is already masked to a couple FA ports and has gatekeepers assigned to it, and is running all the required software.

I have not been able to find the answers to my questions in either the RM5.1 Admin Guide, Product Guide, or SE TimeFinder guide.

Questions:

1. Do I need to mask the bcv volumes to the FA ports the dev server is masked to before attempting to mount the bcv volumes in RM?

2. If I want to mount the volumes read/write are the writes actually written to the bcv volumes or to SAV volumes?

3. Do I need to mask anything else to the mount host? SAV volumes? VDEVs?

Thanks,
Aran

1. Do I need to mask the bcv volumes to the FA ports the dev server is masked to before attempting to mount the bcv volumes in RM?

yes, you need to map and mask BCVs to the same FAs the dev host is connected to.

2. If I want to mount the volumes read/write are the writes actually written to the bcv volumes or to SAV volumes?

once you split BCVs from STD ...BCVs will be come read/write enabled and write will go to them. Same applies to Clones. Now with Snaps ..all writes will go to SAVE pool while reads will come from STD volumes...thus affect performance.

3. Do I need to mask anything else to the mount host? SAV volumes? VDEVs?

just the BCVs or Clones ..whatever you decide to use. If you are doing SNAPs ..then map and mask VDEVS.

there is a SDDF sessions that tracks which blocks changed on the BCV/Clone and STD devices since it was last synched ...so the next time your job runs it should be relatively fast since it does not have to do a full sync again, just an incremental one.

Thanks dynamox, appreciate the quick reply. So when the synch job runs again tonight it will the re-sync take longer since it will have to compare the blocks on the BCV with the STD to determine what to overwrite on the BCV in addition to the changed blocks on the STD?

I am really beginning to wonder if you really have a family.

I have two children myself and don't know where you find the time to write all these posts

I can barely keep up with Stargate SG-1 episodes, let alone the EMC support forums...

Hmmm it's not fair at all .. you live in -almost- the same timezone .. I was having dinner while you were solving your problems !!

AranH1 · Answer

We tried that for a couple of years and the dogs survived. So now we are trying it out on the kids and so far they are surviving too...

Ihihi... I was replying to your posts while holding my little Gabriele on my legs

..

Almost every other show I love is not "on air" .. we are waiting for brand new episodes .. CSI:Miami and CSI:NY will start shortly a new season .. So maybe in the future you won't see me on the forums at night
