Problem Summary

Emulex FC HBA is not visible via 'fcinfo hba-port' or 'luxadm -e port' in OS after installing Solaris 10 Recommended Patch.

Symptoms

- prgdiag -v shows the Oracle Emulex FC HBA.

/SYS/MB/PCIE0     PCIE SUNW,emlxs                        LPe12002-S   2.5GTx8
                        /pci@400/pci@2/pci@0/pci@8/SUNW,emlxs
/SYS/MB/PCIE0     PCIE SUNW,emlxs                        LPe12002-S   2.5GTx8
                        /pci@400/pci@2/pci@0/pci@8/SUNW,emlxs

- But 'modinfo' doesn't show any emlxs driver

Cause

- /etc/driver_aliases, /etc/name_to_major and /etc/driver_classes are missing emlxs entries, instead we see entries like this:

elxfc "pciex10df,e200"
elxfc "pciex10df,e260"

Looks like EMLXelxfc packages were installed but the system was not rebooted until after the Solaris patches were installed

You should be able to look at the pkginfo -l output to see the install dates for the EMLX* packages, the patch install dates in
EXPLORER patch+pkg/* and messages (or last boot history) to see when the system was rebooted. Those could confirm if
suggested explanation above is possible.

This is issue is documented in:

Bug 15729114 - SUNBT7067879 emlxs postinstall scripts must be updated for coexistence with new Emulex driver

Solution

- Restore /etc/driver_aliases, /etc/name_to_major and /etc/driver_classes. There may be a need to restore fp.conf as well.

- Reconfiguration reboot (reboot -- -r)
