Solution

On Solaris, you must stop the qlremote agent before using the Hot Swap feature on QLogic FC adapters.
Please refer to the hardware manual for detailed instructions.

To stop the currently running qlremote agent, do the following:

1. /etc/rc3.d/S99qlremote stop

or

2. kill the process (found with 'ps -ef | grep qlremote')

a. To determine the process identifier (pid) of qlremote, type the following and then press ENTER:

# ps -ef | grep qlremote
root 227 1 0 15:59:55 ? 0:00 /opt/QLogic_Corporation/SANsurfer/qlremote
root 410 409 0 16:01:46 pts/6 0:00 grep qlremote

Note that in the example, the pid is 227.

b. Type the following and then press ENTER:
# kill -TERM pid

The qlremote agent can be re-started from:

/etc/rc3.d/S99qlremote start

If qlremote process is not running then:

1 - Upgrade to latest version of explorer and collect a new explorer

2 - Schedule maintenance window where server can be shutdown for part replacement.
