280r Solaris 9, HBA's added, now some mount points not visible with "df -h"
Hi,
We recently added two HBA's to our SUN 280r in order to connect it with a SAN. After doing this upon entering the command "df -h" three of the mount points namely /308, /d309, and /d310 were not visible. However, we could do a "cd" to them but not to any of their subdirectories. Would anyone know what caused this problem?

John, Sounds like your /etc/vfstab is the culprit. I can only guess as to why this happened. Most likely, someone edited the file, and either removed the entries or used incorrect syntax.-M. McCabe

The vfstab's a good place to start. Do a format and make sure all your disks are still available. If the mounts are specified in the vfstab, I'm surprised you didn't get fsck errors during boot (unless the vfstab's set not to perform it for those filesystems on system startup).

Inserting new hardware (HBA) must have changed hardware path to your disks and comparing "format" output and vfstab cXtYdZ values will confirm.
When allocating LUNs, I would also make sure persistent binding is configured properly.
What kind of HBA are you using (QLogic, Emulex... ?)
