Problem with RHEL AS 4 with Virtual Disk form EVA3000
I have problem with my RHEL AS4 Update 5.
I configured five LUNS.
My problem is that if I reboot server, sometimes change the special files associated to LUN.
This in not a problem with LVM2 but on one of this LUN's I have rawdevices on which I have installed Oracle Clusterware. And after restart Linux change the /dev/sda become /dev/sdb and this is a huge problem because Oracle Clusterware isn't startet properly. I must change /etc/sysconfig/rawdevices and restart service rawdevices?
Any suggestion please?
Thanks seboizm

This shouldn't happen. Can you confirm what multipathing software you're using, if any...
Cheers,
Rob

device-mapper-multipath-0.4.5-21.RHEL4
Do yo think that i can do with /etc/multipath.conf in my situation.

Re: Problem with RHEL AS 4 with Virtual Disk form EVA3000
I'd avoid device-mapper-multipath.
If you're using QLogic HBAs, then the failover options built into the drivers work fine...
Cheers,
Rob

Re: Problem with RHEL AS 4 with Virtual Disk form EVA3000
I have two FC cards:
---info---
HP FC2142SR 4Gb PCI-e, SC, Fibre Channel Adapter on PCI bus 0e device 00 irq 177
---lpfc_drvr_version---
Emulex LightPulse Fibre Channel SCSI driver 8.0.16.32
What can i do with my situation because after restart on one of two nodes change /dev/sda on /dev/sdj and my rawdevices not started and Clusterware and ASM dosen't start properly?
Best regards

Re: Problem with RHEL AS 4 with Virtual Disk form EVA3000
I've never used these cards, but it looks like you should use these drivers:
http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=12169&prodSeriesId=1809835&swItem=co-51731-1&prodNameId=1143949&swEnvOID=2025&swLang=8&taskId=135&mode=4&idx=0
You should use INSTALL -m option to enable failover mode...
Hope this helps,
Regards,
Rob

Re: Problem with RHEL AS 4 with Virtual Disk form EVA3000
hp-lpfc-2007-06-19.tar.gz:
fibreutils-2.3-2.linux.i386.rpm
fibreutils-2.3-2.linux.ia64.rpm
fibreutils-2.3-2.linux.x86_64.rpm
hp-lpfc-7.3.6-6.linux.rpm
hp-lpfc-8.0.16.32-4.linux.rpm
hp-lpfc-8.1.6.8-5.linux.rpm
hp-multipulse-2.2.22-1.linux.rpm
On my server now i have installed:
[root@serv1 ~]# rpm -qa | grep fibreutils
fibreutils-2.3-4
[root@serv1 ~]# rpm -qa | grep hp-lpfc
hp-lpfc-8.0.16.32-4
[root@serv1 ~]# rpm -qa | grep hp-multi
My rpm's is newer than your prpose driver - what can i do in that situation.
Only I don't have hp-multipulse.
On my linux after install them always I isntall last SupportPack with newest driver for dedicated operating system....
You have some proposution.
I think about Firmware - my FC card is - HP FC2142SR 4Gb PCI-e HBA Firmware Version: 2.50A6 - but on hp portal i see 2.72a2 version of firmware. What do you think upgrade firmware that's my problem?
Best regards

Re: Problem with RHEL AS 4 with Virtual Disk form EVA3000
Can you try using "udev"? This will ensure that the device names dont change on reboot.
The new devices will be under /dev/disk/.
