Host System Hangs During Boot

Question

I am in the process of re-configuring a CX300 - I am writing a bash script with all the CLI commands in it, so that what I do is documented and repeatable.
I have created the RAID groups and LUNs, created a Storage group, added the LUNs to the storage group.
Then I added the pre-existing hosts to the storage group.

As an aside, I could not find how to delete the initiator records as they say they are logged in - even through the hosts are turned off.

I have a host running RHEL4 with naviagent and multipath on it.
Having modified the multipath.conf I rebooted the box - but it now hangs during boot-up

Has anyone else seen this - it is proving to be a very difficult problem to diagnose

Curious if you have checked the steps in the "Installation Roadmap
for CX3-Series, CX-Series, AX-Series, and FC-Series
Storage Systems Guide" for Linux Multipath and verified the Failovermode and arraycommonpath setting for the initiators...

Not sure if there is a way to delete initiator records through the cli, but in Navisphere you can right click on the array, select properties, and select Connectivity Status. Select the stale initiator records and click on the Deregister button.

If that still does not remove the initiator records then restart the Navisphere Manager Server.

By the way, you can get loads of CLI commands from EMC Navisphere Command Line Intereface Reference

this is strange because they should not show up as logged-in, but if you want to delete them anyway you will need to enter into engineering mode. Before you do this make sure you are de-registering correct HBAs. Also what did you change in multipath.conf ? We had the same issue and had to boot into single user mode to fix a typo.

Try using the naviseccli command port with option -removeHBA

naviseccli -h [ip address of sp] -user [username] -password [password] port -removeHBA -hbauid [hba id number]

I think the hbauid is the WWN, though I've never used the command this way...you could try -hostip [ip address of host] or -host [hostname] but in the manual it says those options remove records where the initiator is logged out

That's right, records that show the host as logged in cannot be Deregistered via the GUI unless you are engineering mode. Thanks for the catch on that.Message was edited by: AranH
