[Bug 1020436] Re: Cannot read superblock after FC multipath failover

[Peter Petrakis]

Your blacklist definition is wrong. You provided.

"""
blacklist {
        wwid "3600605b0039afe20ff000054052e7d38"
        vendor "SMART"
        product "SMART"
}

defaults {
          user_friendly_names yes
}
"""

wwid cites an entire device, vendor & product cite a different device and must be
included in device { } block.  If you look at the "show config" output, you'll note
that your blacklisted device by vendor/product isn't there.


Change to:

"""
blacklist {
  wwid "3600605b0039afe20ff000054052e7d38"
  device {
    vendor   "SMART"
    product "SMART"
  }
}

defaults {
          user_friendly_names yes
}
"""

update your initrd (multipath.conf is copied there) and reboot.

Also, it would be nice to see a list of all your storage devices. I prefer
lsscsi, e.g.
root at nashira:~# lsscsi 
[0:0:0:0]    cd/dvd  hp       DVD A  DS8A5LH   1HE3  /dev/sr0
[2:0:0:0]    disk    NETAPP   LUN              8020  /dev/sdb
[2:0:1:0]    disk    NETAPP   LUN              8020  /dev/sdd
[3:0:0:0]    storage HP       P410i            3.66  -       
[3:0:0:1]    disk    HP       LOGICAL VOLUME   3.66  /dev/sda
[5:0:0:0]    disk    NETAPP   LUN              8020  /dev/sdc
[5:0:1:0]    disk    NETAPP   LUN              8020  /dev/sde

Finally, since this is FC, how is it zoned? Detailed port level topology please.
Thanks.
