vxdisk list showing devices no longer present
When recabled to an EVA, the device names have changed. The volume groups have started fine though, including the LVM ones.
However vxdisk list shows disknames that no longer exist, although the device path is there.

Re: vxdisk list showing devices no longer present
Different cabling = different device files, no doubt.
Are all the disks used by LVM?
Did you vgexport/vgimport?
And BTW, 1 disk and 2 alternate paths sounds like 1 path is missing ...
Hope this helps!
Regards
Torsten.

Re: vxdisk list showing devices no longer present
The final part of any successful migration.
Is the house keeping.
"However vxdisk list shows disknames that no longer exist, although the device path is there."
You should know what to do now.
Remove the special files and directors.
Kind Regards,
Terry Giblin

Re: vxdisk list showing devices no longer present
Terry, the missing disks are the ones that are displayed with vxdisk list. So, can I just remove the special files and directories relating to these without affecting VxVM? The correct disks only show when you issue vxdisk list

Re: vxdisk list showing devices no longer present
VxVM is agnostic to device name changes - which means as long as all the component disks of each disk is present, then VxVM will discover them.
If vxdisk lists show "devices" that are no longer present and ALL your LVM and VXVM VGs and DGs are present -- then you can just ignore them or if they annoy you - you can remove them...
Can you quickly shoot us a "vxprint -Aht" and "vxdisk list"?

Re: vxdisk list showing devices no longer present
I am concerned that this is a cluster and that not resolving the problem could result in an issue during failover.
Also, if I'm able to just remove the erroneous file references in /dev as has been suggested, will this affect a running environment especially as vxdisk list shows these as the primary (if you like) devices.

Re: vxdisk list showing devices no longer present
If you think we can HELP...
Shoot as the output requested above.
Cluster or No CLuster, VxVM t'shooting scripts are practically the same -- specially when addressing "dm" disks.
