How to create Linux RH 4.0 disk mounted from EVA3000

Davide Depaoli_3 — Mon, 18 Jul 2005 04:14:24 GMT

Hello,
I'm not a Linux sysadm, but I need to install a new volume on a RedHat 4.0 from EVA3000.

I have:
1) installed on the server the FCA2214 Qlogic drivers + Path Failover utility.

2) created a VDisk on EVA3000
3) presented the Vdisk to the server

At tne reboot the server has discovered and configured two HBAs.

now my problem is how to view and configure the EVA3000 volume on the server.

The server cannot automatically discover new disks.

Anyone may help me about this ?

thanks in advance
kind regards
Davide

Another, maybe, important information about this SAN is that the FC switches are zoned, because there are 2 server with hba and no failover sw.

thanks Davide

To find out if it is a low-level problem, I would first go into the FCA2214 BIOS and see if the adapters are able to access the EVA and any virtual disks presented.

While booting the server, watch for the announcemenet to press ALT/Q or CTRL/Q (I never remember the exact message). You are then presented with an easy menu from which you can do the scan.

Done the BIOS test and all two HBAs doesn't seen devices.

During the server boot the message "Bios is not installed" for the HBAs.

The switch ports where these HBAs are connected are not part of the configured zones.
If I go to switch GUI on the port where HBA is connected, I see the wwn of the hba.
Firmware revisions:

EVA3000: 3.014
Switches: v4.0.2a
HBAs driver version 8.00.02

thanks Davide

My dubt is that on zoning. I'm not very expert about this argument, but if the FC switches are zoned, every other configuration must be zoned, even if there are two HBAs on the server ?
In this case I must to create a new zone for my Linux server ?

If you are new to Linux System Administration, i must ask if did you run fdisk -l to check the precense of the disks?

You should see devices like /dev/sda, /dev/sdb, /dev/sdc, etc, for every disks detected.

If you have internal SCSI disks, you will see a /dev/sd device for those too, so, if you have two internal SCSI disks, and one unit configured on the EVA, is probably that you will have:

/dev/sda -> internal disk
/dev/sdb -> internal disk
/dev/sdc -> eva vdisk

fdisk -l without parameters doesn't work (return no info).

I have configured FC switches with a new zone for this server, and now I see (at FC level) the LUN from EVA on thew server (with SANSurfer).

I cannot be able to discover from Operating system the new disk.

SOLVED !!!!!

zoning on FC switches is working and Linux, after a lot of reboots have discovered the special file /dev/sda.

formatted, mounted and is working.
