fdisk weirdness.

fdisk weirdness.

[C'est Pierre]

Greetings,

I've been trying to setup a server for a cluster that is attached to a
fibre channel storage (an HP EVA 3000 hsv100). Prior to allocating a
vdisk on the storage for this server, whenever I'd issue "fdisk -l",
it wouldn't print anything at all. After correctly alocating the disk
on the Storage, it shown 2 disks, sda and sdb. At this point, I assume
they're 2 LUNS for the same vdisk, being that the Storage attached
through two different FC cards for redundancy/failover - feel free to
correct me if I am wrong. However, the /dev/cciss/c0d0[pN] (compaq
smartarray or something) doesn't show up on it's output.

Any hints?

Thank you,
Pierre

You will probably want to install one of HPs failover-capable drivers:
http://h20000.www2.hp.com/bizsupport/TechSupport/DriverDownload.jsp?pnameOID=315741&locale=en_US&taskId=135&prodSeriesId=315739&prodTypeId=12169&swEnvOID=2026


This is for 2 GBit/s Qlogic-HBA, more or less regardless of the OEM.
(worked for IBM, too, for us).
