Fabric maintenance
You must apply a workaround on the host before you can begin fabric maintenance.
Apply the following workaround on the Red Hat Enterprise Linux® 4 Update 4 host before starting fabric maintenance, including the system software upload:
$>vi /bin/bug23366.sh
#!/bin/bash
for f in `grep offline /sys/bus/scsi/drivers/sd/*/state | sed 's/^\(.*state\):.*$/\1/g'`;
do echo running > $f;
done
$>crontab -e
