Ghost luns" shown with Hitachi Lightning (SAN)
This document (3820721) is provided subject to the disclaimer at the end of this document.
After connecting the cable while the Fibre Channel Controller module is loaded and/or during boot there are many (max. 16384) "Ghost Devices" per Controller that are not needed or used. These devices can be found in /proc/scsi/sg/devices and /proc/scsi/sg/device_strs Notification for discovery can be found in /var/log/messages
The Flag bit "0x1000000" (PQ3) works different on SLES10 compared to SLES9 and SLES8.
With the use of the kernel-cmdline"scsi_mod.dev_flags=HITACHI:OPEN-E:0x20240"the PQ3 bit for the OPEN-E Devices will be reset und the "ghost luns" are not shown.
So you edit in
the entry for the kernel commandline and append
then you reboot and the "ghost luns" are gone
