admsnap error
Hi,
I have a customer that is trying to do snapshots on a CX500. They are receiving the following errors when they initiate an admsnap command:
C:\>admsnap flush -o q:
Error looking up object "Q:".
Error: 0x3E16000D (The object name specified was invalid or incorrectly formatted)
C:\>admsnap deactivate -s Q_Bk_Mon
No devices were found that could deactivate this session.
These are the mount and unmount commands which they are using:
@echo off
cls
admsnap flush -o q:
admsnap deactivate -s Q_Bk_Mon
admsnap flush -o r:
admsnap deactivate -s R_Bk_Mon
admsnap flush -o w:
admsnap deactivate -s W_Bk_Mon
admsnap flush -o s:
admsnap deactivate -s S_Bk_Mon
admsnap flush -o p:
admsnap deactivate -s P_Bk_Mon
admsnap flush -o y:
admsnap deactivate -s Y_Bk_Mon
admsnap flush -o z:
admsnap deactivate -s Z_Bk_Mon
pause
@echo off
cls
admsnap activate -s Q_Bk_Mon -d Q:
admsnap activate -s R_Bk_Mon -d R:
admsnap activate -s W_Bk_Mon -d W:
admsnap activate -s S_Bk_Mon -d S:
admsnap activate -s P_Bk_Mon -d P:
admsnap activate -s Y_Bk_Mon -d Y:
admsnap activate -s Z_Bk_Mon -d Z:
pause
Any ideas what may be causing the problem?
Thanks,
Dan

The way I understand it, you:
- start a session on the server that own the source LUN (after flushing to help ensure a clean filesystem for the snapshot session)
- activate the session on the server that needs to access the snapshot (session)
Then, once done with the snapshot you:
- de-activate the session on the server that needs to access the snapshot
- stop the session on the server that owns the source LUN
