RedHat 4.2 loses disk after POST


I have 2-32 bit Redhat 4.2 (2.6.9-67.0.15.ELsmp) servers connected through a Brocade switch to 2 disk arrays. One array is a NexStor8f and the other is an NexStor18f. The NexStor8f is set to use addresses 1-8 and the Nexstor18f is set to use 18-35.

On boot, the POST for the fibre card on both servers shows it acquires 26 disks and the controller at address 15. However, the dmesg command shows that it only configures the first 25 disks and leaves the last disk off of the NexStor18f.

Has anyone seen this behavior? I am using a LSI Logic FC909 fibre card in each node.

During the card configuration it allows reset to address 27 for the card but on reboot it forgets this and resets to 15 which appears to be causing the issue, for some reason the card bios is not being updated, anyone have a work around?

The arrays are both connected through a single connection to the brocade as are the servers. The switch is set up with a single zone which includes the two servers and disk arrays.

Thanks.

Mike

The problem was the FC909 HBAs, I pulled them and replaced them with QLA2200s and now all disks are presented.
