RHEL3 & RHEL4 and SAN - EVA5000

[Finnur Örn Guðmundsson - TM Software Skyggnir]

Hello,

I'm running RHEL3 and RHEL4 on IBM Blades (HS20). They are booted of SAN.

I have been wanting to be able to add drives from the SAN on-the-fly. After reading alot of text i came to the conclusion that RHEL4 is not able to do this...yet atleast unless you install the driver from Qlogic, (dont use the come that comes with the RHEL4 kernels)...witch is pretty sad for a enterprise grade distrib....atleast include rescannable san drivers please! ;).

But,

RHEL3 is supposed to be able to do this. I have tried pretty much anything out there as:

scsidev 2.35
rescan-scsi-bus.sh

And here is something i tried:
#!/bin/bash
echo "scsi-qlascan" > /proc/scsi/qla2300/0 (After this i dont see any extra lun if i cat /proc/scsi/qla2300/0)
echo "scsi-qlascan" > /proc/scsi/qla2300/1
echo "scsi add-single-device 0 1 2 3" >/proc/scsi/scsi


The system is running 2.4.21-32.Elsmp.

Using the RHEL3 Qlogic drivers.


The HSV is: EVA 5000.

Has anyone done this on EVA´n´IBM Blades?.......

Is the only way to install another Qlogic driver?

Kær kveðja / Best regards,
