qla2300 woes continue 2005-10-26 - By Lee Whatley, Contractor

Hello again list,
I thought that I had worked out all of my san problems once I was able
to actually see all of my luns, but alas even though I can see them I
can't seem to write to them.
This is on my AMD64 system running RHEL ES v3 U6. The storage array is
an STK D178 and is directly attached to the system via a Qlogic 2300 hba.
Basically what happens is, I can see the disks on boot. I can run fdisk
and partition them, but the partitions aren't being written to the
disks. Here is what an fdisk session looks like:
-- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ------
[root@(protected) root]# fdisk /dev/sdg
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF
disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.
The number of cylinders for this disk is set to 71376.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

Here are the options I am using in my modules.conf for my ql2300:
options scsi_mod max_scsi_luns=128 scsi_allow_ghost_devices=1
options sd_mod max_scsi_disks_fs=32
options qla2300 ConfigRequired=0 ql2xuseextopts=1
Thanks in advance for any help or advice,
-Lee
