How to remove all lunpaths associated with a tgtpath

0xGK — Thu, 02 May 2013 18:34:17 GMT

I'm looking for a quick and easy way to remove all the lunpaths associated with a particular tgtpath. Essentially we lost a port on one of our storage devices. The storage team "repaired" this by presenting a different port to the servers. That means we need to remove the failed path and all associated device files. I am trying to avoid a reboot to do this. I have 12 impacted servers with hundreds of LUNs to contend with.

The failed tgtpath is: 34/0/2/0/0/0/0/4/0/0/0.0x500a098887a9aa96

There are 62 associated lunpaths with this tgtpath.

I tried to use scsimgr since the man page seems to imply that -H can accept a target path, but that doesn't work.

[root@preodbu1a]# scsimgr disable -H 34/0/2/0/0/0/0/4/0/0/0.0x500a098887a9aa96
scsimgr: ERROR: Invalid object identifier.
Command disable expects a LUN or LUN path identifier

I've disabled the lunpaths which prevents the system from accessing the LUNs over these paths. So far I see:

Any easy way to get rid of this tgtpath, lunpaths, and associated device files without reboot?

Answering my own question...

# rmsf -H tgtpath

Too easy!
