Replace old Smart Array with SA5300

[Ayman Altounji]

Can one do an in-place upgrade of Linux running one of the old generation Smart Array controllers (using cpqarray) with the newer Smart Array 5300 Controller (using cciss)? If so, how?

I tried to do this on Red Hat 7.3 (2.4.18-3), but the boot would hang with the following error message (just the last few lines reproduced here):

failed to exec /sbin/modprobe -s -k block-majort-104 errno =2
mont: error 6 mounting ext3
pivotroot: pivot_root (/sysroot,/sysroot/initrd) failed: 2
kernel panic: No init found. Try passing init= option to kernel

(this type of error message has happened to me a couple of times under different circumstances when I did somethin kernel-related, but I have never been able to fix it and had to reinstall)

I also tried the following without any luck:
1 modifying /boot/grub/grub.conf entries from ../ida/.. to ../cciss/..
2 grub-install /dev/cciss/c0d0p1 (which recreates /boot/grub/device.map to reflect the new device name)
(fd0) /dev/fd0
(hd0) /dev/cciss/c0d0
3 change entries in /etc/fstab from ../ida/.. to ../cciss/.. (unnecessary for RH, which uses ext2 labels, not device names to refer to these devices
