Subject: Re: Losing SAN Adapters with RHEL5 servers after patching

Hi

Is it possible that the zfcp module is not being loaded after the reboot?
Can you issue this command after the reboot:
lsmod | grep fcp
Can you also make sure this udev rule is in place and send it content:
/etc/udev/rules.d/56-zfcp.rules

Good luck
Offer Baruch
