Description Bob Plankers 2003-04-21 17:01:54 EDT

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 
1.0.3705; .NET CLR 1.1.4322)

Description of problem:
With the advent of fibre channel storage and such it would be cool if you could 
change the value of CONFIG_SD_EXTRA_DEVS in the default kernels, so that people 
with larger storage setups will work "out of the box" (one of the great things 
about RHL, actually). Without this, users are limited to only 40 SCSI devices 
on the machine, and require custom built kernels to get things working.

Set CONFIG_SD_EXTRA_DEVS=128 (the default is 40)

This is true in RHL 7.x and 8.0.

All the other settings necessary for proper fibre channel support (the setting 
of CONFIG_SCSI_MULTI_LUN=y) can be done as a runtime/modules.conf option.

Thank you!

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.Attach 45 SCSI devices (LUNs on a fibre channel disk array, etc.).
2.Reboot -- only the first 40 get sd names (/dev/sdXX).
3.Change it in the kernel, reboot, it works. :-)
