SCSI problem with sym53c8xx driver
I have a HP Proliant DL380 server with an onboard cciss scsi controller. This one is used for 4 harddisks. An additional adapter is in the server for a StorageTek L80 Robotic changer. This is a Symbios adapter.
The OS is RedHat AS 2.1.
In the modules.conf:
alias scsi_hostadapter cciss
alias scsi_hostadapter1 sym53c8xx
The problem is that the sym53c8xx driver is not loaded at boot time. When I do a manual insmod sym53c8xx the robotic changer is found.
Why does Linux not load the driver? It does load the cciss driver.
Regards,
Leon

Re: SCSI problem with sym53c8xx driver
I ask because in a scsi install with a different OS that is the driver I got for a scsi card that was detected but the OS didn't know the driver for it.
The system blew up spectacularly when I actaully tried bringing up the scsi card after the fact.
Probably not helpful, but I thought I'd let you know anyway.

Re: SCSI problem with sym53c8xx driver
You must check if in the boot process
the module is tried to insert into.
Also the linux system work this way that
if no use for module than he not loaded.

Re: SCSI problem with sym53c8xx driver
Is the 'st' module getting inserted at bootup?
In any case, just throw a 'modprobe' in your rc.local routines.. it'll force the loading of the module upon boot-up..

Re: SCSI problem with sym53c8xx driver
Did you check whether the driver is listed in /etc/modules.conf for being loaded during start-up?
As the others wrote, it is vitally important not to get confused with the numerous NCR/Symbios drivers floating around. So does the driver work properly when you do the insmod manually?

Christoph

Re: SCSI problem with sym53c8xx driver
"dmesg | grep sym"
dmesg prints out the kernel messages.. then it will grep for the sym driver and see if it loaded correctly.. you can also just pipe it into more or less to read the rest of the messages
"dmesg | more" or "dmesg | less"
From there you can figure out if it got loaded at runtime or not!

Re: SCSI problem with sym53c8xx driver
Currently, your system failed to install scsi driver....just try if you can insert the scsi driver form command line.
# lsmod (See if sym53c8xx is in kernel)
# insmod sym53c8xx
# lsmod (confirm the driver is in or not)
If you success to load the driver, what you need is configure initrd.
You just write "alias scsi_hostadapter1 sym53c8xx" into /etc/modules.conf. This is not enough.
# /sbin/mkinitrd /boot/initrd-kernel-version.img your-kernel-version
your-kernel-version = "uname -r"
After this command, edit /etc/lilo.conf or /etc/grub.conf. If you are using lilo, /sbin/lilo is needed after you modify it.
If you failed to load the sym53c8xx manually, I guess something wrong with your system.
Say, system failed to detect the scsi card.
see # cat /proc/pci or lspci -vt to see if your kernel can detect the scsi card.
good luck

Re: SCSI problem with sym53c8xx driver
Sorry for the late response, I did not recieve mail notifications.
The driver does not load at boot time. No attempts either. It is the correct driver, because a manual insmod does work fine. And the scsi device is working fine as well after that.
I'm going to try the solution of Masanari Iida and let the results know.
