In 2.4.19pre1 a patch was merged into mainline which introduced a flag
BLIST_LARGELUN and set it for EMC Symmetrix devices. Some distributors
(incl. RH and SuSE) did ship kernels with this patch included.
(An older patch for 2.4.16 exists as well.)
The flag does allow a device to use more than 8 LUNs despite it reporting
as SCSI Version 2 devices (which can not support more than 8 LUNs normally
The flag also needs to be set for some more devices, look for DGC, DELL, CMD
and CNSi/CNSI devices that already have the BLIST_SPARSELUN flag.
But as you did not post the output of /proc/scsi/scsi nor the syslog
meesages from your SCSI subsystem nobody knows what devices you're using or
what actually happens. Just speculations ...
