Sun Fibre Channel Port Driver (qlc/fp) Issues

A SENA device that uses the qlc/fp drivers is considered a different physical device than a SENA device that uses the socal/sf stack. SENA devices do not support mixed configurations where qlc/fp and socal/sf drivers service a single SENA device. Therefore, the two devices cannot be combined in an AP metadevice.

Revising the firmware on a physical SENA device using socal/sf drivers to use qlc/fp drivers for your Fibre Channel controllers is the same as replacing the hardware with a different type of controller. (The converse is also true.) You must unconfigure Alternate Pathing on such controllers before you revise the firmware. For example:

# apdisk -d sf:0 
# apdb -C

Revise the SENA firmware.

After you have performed the revision, recreate your pathgroups using the new device names, for example:

# apdisk -c -pfp:0 -a fp:1
# apdb -C

If you change firmware without unconfiguring AP, file systems available from the new alternately-pathed controllers may not be accessible. If those file systems are required during boot, your system can become unbootable.
