Detecting New SAN LUN in RHEL5

[Young, Mike]

Wow, this might have been just what I needed.. Too bad I didn't have that info last night.

I'll try it "next time".

Thanks,
Mike.

That's a cool site:

If you need re-do a SCSI scan, you can do

echo "- - -" > /sys/class/scsi_host/host0/scan

Where host0 is replaced by the HBA you wish to use. You also can do a
fabric rediscover like this:

echo "1" > /sys/class/fc_host/host0/issue_lip
echo "- - -" > /sys/class/scsi_host/host0/scan
