Linux limitation of amount of SCSI buses
Hi All,
I'm connecting few cards with 24 buses and Linux gives me only 15 buses.
Is there any limitation in Linux SCSI subsystem within kernel 2.4.x of the number of SCSI buses ? Each bus has a single target and a single LUN.
Regards,
Rabeeh

Does each card have multiple channels (i.e., 24)? If so you may need to set max_channel to a higher value.
If each card has a single bus there may be a instance limit that the driver you are using will support.
What driver are you using?

Each card has 8 buses ; total 3 cards. On each bus I have a single target that has single LUN. If I work with a single adapter I can see 8 buses.

Internal driver that is under development.
