Subject: zFCP question for RHEL54
I'm running into issues adding zFCP LUNS to a clustered zLinux server. The
primary servers sees the disk with no issues and have multipath'ing turned on.
Both servers should be pointing to the same scsi disk. What am I missing? Any
ideas? I've tried rebooting with no results. I do see the following error in
/var/log/messages
Dec 6 14:28:15 wil-zstsccdbtstbu01 kernel: zfcp: warning: failed gid_pn
nameserver request for wwpn 0x50060e800571f006 for adapter 0.0.dc00
Dec 6 14:28:15 wil-zstsccdbtstbu01 kernel: zfcp: port erp failed (adapter
0.0.dc00, wwpn=0x50060e800571f006)
I see this for each adapter. I did try to remove the unit and port vary the
adapters offline and tried it again with the same results.
The server that works

My first though was whether there'd be enough humor in an EBCDIC version.
