Add EMC Powerpathed boot from SAN support

[Bruno Cornec]

Has anyone tried using Mondo with EMC Powerpathed boot from SAN drives? It works fine with boot from SAN drives, that are not running powerpath or mpxio.

[Bruno Cornec]

Could ou provide a full mondoarchive.log/mondorestore.log corresponding to such an operation please ?

[Bruno Cornec]

FYI, multipath, such as provided by RHEL 5.2 will be supported in 2.2.8. The beta available at ​ftp://ftp.mondorescue.org/test is already containing that feature.

For EMC I'm ready to add what is needed providing I receive information on how to do it.

Added the mondorestore logfile with powerpathed devices.

Thanks.

I'd also need your /var/log/mondoarchive.log from the original system please.

I made a beta version of mondo for you to try at ​ftp://ftp.mondorescue.org/test/rhel/5 (mindi 2.0.6 + mondo 2.2.9) that should improve EMC support. Please report what you find with this version (and I'll still need the 2 logs).

Thanks Bruno, but it didn't work. I'm attaching the logfiles for you.

It still can't find the /etc/emcpowera devices.

Hummm. It seems that the modules goes on to the backup media but are unable to be loaded with modprobe.

Do you have a special procedure on the original system ? a startup script ?

What gives rpm -ql rpm -qf /lib/modules/2.6.18-53.1.6.el5/powerpath/emcp.ko

[Anthony Cicone]

Bruno,

Sorry my email bounced back, here is the update I sent:

Yes PowerPath is started by a startup script.

/etc/init.d/PowerPath

I'm including these scripts and the /etc/rc.local and /etc/rc.sysinit which calls the startup script.

Thanks for your help.
