Map Redhat 2.1 devices to MAS 1500 Lun with qla2312 HBA

[Kenneth Dahl]

Hi,

I can't map the Lun on the MSA 1500 SAN to the devices on the /dev folder. There are some devices called sgb-p linked to sg0-15.

I have checked the /proc/scsi/qla2300/2 file:

QLogic PCI to Fibre Channel Host Adapter for QLA2340 :

Have you restarted the server after creating the LUN? Is SPP enabled? Is the lun presented to the host? What is the output of fdisk -l.

[Kenneth Dahl]

Yes I have.
I tried to block the connection in the Fiber switch, and reboot the server. Then the last part of the file was empty, so the driver Recognize the LUN.

The fdisk -l shows;

[root@dkfs3lx root]# fdisk -l

Disk /dev/hdc: 255 heads, 63 sectors, 4863 cylinders
Units = cylinders of 16065 * 512 bytes

Device Boot Start End Blocks Id System
/dev/hdc1 * 1 13 104391 83 Linux
/dev/hdc2 14 274 2096482+ 82 Linux swap
/dev/hdc3 275 4863 36861142+ 83 Linux

The qla2300 driver has created a set of devices in the /dev folder.

Can you see the connections in the MSA1500 for the Linux HBA?. What is the status of the link?

I would install fibreutils and sansurfer and check the HBA status/connections with these utilities (SanSurfer seems to not be available for RHEL 2.1).
