Command Line to place a LUN in an "offline" state

[rpeabody]

I was wondering if there was a command line available in the ESX server to place a LUN in an "offline" state.

What are you trying to do?

I think you would be better off doing something at the storage level such as making hte LUN read-only os simply masking it from the ESX hosts?

If you want to turn a path to a lun off you can do something like this:

log]# esxcfg-mpath --path=vmhba1:0:0 --state=off --lun=vmhba1:0:0

Setting vmhba1:0:0 -- vmhba1:0:0 state to off

Disk vmhba1:0:0 /dev/sda (258052MB) has 2 paths and policy of Fixed
