Support for lun > 7 on HP's XP128 storage

Support for lun > 7 on HP's XP128 storage

[Ionut Nistor]

Hello,

I am running a 2.4.18-ac3 kernel on a ia32 system.
This system is connected to a SAN via an Emulex LP8000 HBA. The storage is
HP's XP128. The controller on the storage reports scsi version 2 however,
luns with ID > 7 are also supported. When the HBA driver is loaded, no LUNs
are detected but if "scsi add-single-device" is used later, the luns are
visible.

Maybe it should be added to the kernel with BLIST_LARGELUN - correct me if I
am wrong.

Thanks,
Ionut

Sorry for being coming back on the same issue but should this (blacklisting
for XP) not be included in the kernel?

Thanks,
Ionut
