Creating a New file system on Redhat from EVA 3000

Hi;
Am a hp-ux guy and i have little experience on Redhat. This is my issue;
i have 2 disks already presented and configured on the RH machine. ( i didnt do it but it works).

A third FS is needed 500GB, which i have created and presented to the server. But when i ran the fdisk -l i cant figure it any where. then i ran the
echo 1 > /sys/class/fc_host/host1/issue_lip
and
echo 1 > /sys/class/fc_host/host2/issue_lip
and still no change after running the fdisk -l.

but i do get an error;

# fdisk -l

but i beleive its cause not multi pathing is used on the existing fs.

Guys help me cause this is a live environment and the FS is needed ASAP.

Hi,

You should hopefully see the relevant disks in the output of "dmesg".

If you're not running any multipathing software, then each LUN from the EVA will be seen 4 times, so be sure you're using the right one. You should hopefully be able to see the WWNs of the LUNs to be able to differentiate between them.

Hope this helps,

Regards,

Rob

Re: Creating a New file system on Redhat from EVA 3000

If this is an HP server, you should install the Proliant Support Pack and enable QLogic failover. You will need to reboot the server.

To see the LUN, you can try with the rescan-scsi-bus.sh script. The fibreutils package provides the "hp_rescan -a" command to detect new LUN devices.
