[2.6.25.1] qla2xxx can't see more than 4 drives

[Gerhard Mack]

I have an array witjh 6 drives in it and if use the card's utilities on 
boot it sees all of them but for some reason Linux only sees 4 drives.

Am I running into a limit?  I can see both drives if I remove other drives 
from the array.

Could you load the driver with the ql2xextended_error_logging module
parameter set to 1 and send the resultant driver logs?  Also, it would
could you also send the output of the following after the driver is
loaded:

$ cat /sys/class/fc_host/host<host_no>
$ cat /sys/class/scsi_host/host<host_no>/*
$ cat /sys/class/fc_remote_ports/*

where host_no corresponds to the SCSI host-number assigned to the HBA.

Hmm, qla2xxx has a 'split' port-discovery model based on topology.
Switched fabric (P2P) discovery and logins are managed by the driver.
FC_AL topology discovery and logins are managed by firmware.  The
driver (qla2xxx) simply asks the firmware for a list of recognized
ports, as you've noted the driver (and indirectly, firmware), only
recognized 4 ports during LIPA/LIHA/LISA address negotiation:

You mentioned that the 'BIOS' configuration program recognizes 6
devices, have there been any changes made via the BIOS utility to

* assign a hard-loop id?
* acquire a loop-id during LIPA?

or any changes above and beyond 'default' settings?  If so, could you
'retrore' default settings within BIOS utility?

Hmm your right.. it's only showing 4 drives in the BIOS utility.  Don't 
know why I recall seeing more ealier.

It's back to default and only showing 4 drives.

Ok, so at least the BIOS and driver views of the topology are
consistent...  The firmware supports up to 126 devices in a FCAL
topology, so there's no HBA limit that is being run into here.

You mentioned that if you remove the originally visible drives, then
the driver/BIOS can see the previously non-visible drives -- perhaps
there is some limitation with the storage enclosure you are using...
