Recently I ran into an interesting issue when my SAN administrator presented new storage to an HP-UX host. Multiple luns were presented, but two of them do not show properly in the sanlun command. Sanlun lun show -b all and -p all do not display all of the new luns, but sanlun lun show -v does. In addition the sanlun lun show -v displays the new luns with but the paths are shown as the Agile disks. On working luns the paths are shown as the pv-links. Attached is an example of what I am seeing. I have cleaned up all NO_HW devices/disks as well as any invalid hardware paths that were present on the server.
Is there some way to "fix" the lun so that I can see it in the -b and -p output? I've also tried having my SAN administrator re-map the luns to new lun numbers and that did not resolve the problem. I believe the issue I am seeing is also related to a seperate problem I have with snapdrive functionality on the host. Sanlun version is 5.1.123.0013.

After doing some massive cleanup on the box to remove old device files, luns, non-existant volumegroups, and a host of other issues I was unable to fix this issue. I ended up having to upgrade snapdrive to the 6.x version before it would work properly.
