Ok, after stumbling over scsi_static_device_list[] __initdata in
drivers/scsi/scsi_devinfo.c I just added the line
{"SRE", "OPTAC Tool", NULL, BLIST_NOT_LOCKABLE},
to it and - pooof - this thin magically works.
This leads to my next question: Adding the entry dynamically yields
# echo 'SRE:OPTAC Tool:0x80000' >/proc/scsi/device_info
# cat /proc/scsi/device_info | grep OPTAC
'SRE ' 'OPTAC Tool ' 0x80000
Adding it to the static list via patching scsi_devinfo.c (I don't want to do
that on production servers) yields:
# cat /proc/scsi/device_info | grep OPTAC
'SRE' 'OPTAC Tool' 0x80000
which is quite a difference! How do I get the SRE-entry
into /proc/scsi/device_info without those )%$!(##'!-spaces?
