As the title indicates -- I have a new Dell R730xd running Centos 6.7 with all updates loaded, etc. I also installed the Emulex utilities, etc.

The issue is that nothing I try (reboot / rescan-scsi-bus.sh / manually) is making any of the LUNS appear to the OS. I am not seeing anything in /dev/disk/by-path for anything but the 2 native SCSI drives.

The output of the hbacmd listhbas comes back ok.

I am getting these messages in the kernel -- but google research showed they are "harmless" (famous last words) .. the various UP and Downs are from doing the rescans (or so it appears)...

Upfront -- I am a SAN newbie -- but I've read a lot of doc on how to do it -- but the basic just seeing the LUNs is throwing me for a loop!

I just installed the latest Emulex Linux driver 10.6.144.21 but that didn't resolve or change anything.

Thanks in advance!

  • Can you confirm that the FC switeches zoning is ok ? Otherwise the HBAs won't be able to reach the SAN array – sfk Nov 11 '15 at 08:05
  • I'll double check with the SAN guys -- but they indicated it was done properly. The status of the fc_host also appeared to say (I don't remember exactly which thing I checked) that it was connected to a Fabric and had a speed, etc. and some traffic was being transmitted. So at least the physical connection to the FC Switch seemed to be ok. – S McDowall Nov 12 '15 at 15:43
  • What you describe is basically that the HBA logs into the FC Fabric. My question was about zoning, i.e. does a zone exist to allows the HBA to access the SAN array (EVA controllers) ? – sfk Nov 13 '15 at 15:59
  • Solved! The SAN guys by-passed the FC Fabric switch (which I guess was having some odd problems anyway) - -and viola -- everything came up just fine and the LUNS appeared, etc. Everything is happy. – S McDowall Nov 13 '15 at 22:42

So, at some point we'll have to figure out what's wrong with the FC Brocade thing, but that's a problem for a different day.
