@Joe Please attach the latest multipath.conf and lvm.conf responsible for this stream of messages. If you could move over that logs and other stuff from salesforce into this bug that would be ideal.

[Bug 824790] Re: IBM DS3400 Will Not Bring Up Second Path
So the paths not showing up with a config file error, a few well
placed regexp and a proper blacklist to filter out the internal disks
solved that. Also added scsi_dh_rdac to initial ramdisk. Now the paths
are up, and stay up. However when we tried testing failover using
a scsi "delete" of the primary member. The secondary never became
active.
We asked the customer to check with any additional SAN side
config, like automatic lun transfer, is necessary. Depending on how
that turns it we may actually have a real failover bug.
Working multipath config, taken almost verbatim from the IBM
documentation: Section 5-10.

[Bug 824790] Re: IBM DS3400 Will Not Bring Up Second Path
In an addition to the MP issues, LVM was misconfigured. We attempt to repair this on one of the blades but the config file just wouldn't *take*. I suspect there was something else going, especially since we didn't even have direct access to the console and was forced to relay directives to the customer to execute. I set up a mock test environment to test the the filtering by PCI device. root@kickseed:/dev/disk/by-path# ls -l total 0 lrwxrwxrwx 1 root root 8 2011-08-15 10:04 pci-:00:00.9-scsi-0:0:0:2 -> /dev/sdc lrwxrwxrwx 1 root root 9 2011-08-15 10:04 pci-:00:00.9-scsi-0:0:0:2-part1 -> /dev/sdc1 lrwxrwxrwx 1 root root 8 2011-08-15 10:04 pci-:00:00.9-scsi-0:0:0:3 -> /dev/sdd lrwxrwxrwx 1 root root 9 2011-08-15 10:04 pci-:00:00.9-scsi-0:0:0:3-part1 -> /dev/sdd1 lrwxrwxrwx 1 root root 8 2011-08-15 10:02 pci-:00:1f.2-scsi-0:0:0:0 -> /dev/sda lrwxrwxrwx 1 root root 9 2011-08-15 10:03 pci-:00:1f.2-scsi-0:0:0:0-part1 -> /dev/sda1 lrwxrwxrwx 1 root root 8 2011-08-15 10:03 pci-:00:1f.2-scsi-0:0:0:1 -> /dev/sdb lrwxrwxrwx 1 root root 9 2011-08-15 10:03 pci-:00:1f.2-scsi-0:0:0:1-part1 -> /dev/sdb1 Then, I commented out the existing "filter" directive on /etc/lvm/lvm.conf and tested: filter = ["a|/dev/disk/by-path/pci-:00:00.9-scsi.*|", "r/.*/" ] and filter = ["a|/dev/disk/by-path/pci-:00:1f.2-scsi.*|", "r/.*/" ] lvmdiskscan confirms the filter directives. root@kickseed:/dev/disk/by-path# lvmdiskscan /dev/disk/by-path/pci-:00:1f.2-scsi-0:0:0:0-part1 [ 7.45 GiB] /dev/disk/by-path/pci-:00:1f.2-scsi-0:0:0:1-part1 [ 10.00 GiB] 0 disks 2 partitions 0 LVM physical volume whole disks 0 LVM physical volumes root@kickseed:/dev/disk/by-path# lvmdiskscan /dev/disk/by-path/pci-:00:00.9-scsi-0:0:0:2-part1 [ 10.00 GiB] /dev/disk/by-path/pci-:00:00.9-scsi-0:0:0:3-part1 [ 10.00 GiB] 0 disks 2 partitions 0 LVM physical volume whole disks 0 LVM physical volumes I'm going to leave this part of the effort to customer support.
