Description vijay 2008-12-08 11:17:12 UTC 
Description of problem:

The mpath devices are not created for cciss devices. Due to this the multipath support for the root partition on CCISS devices is not available.

How reproducible:
Providing the "mpath" kernel parameter at the installation prompt fails to create the multipath devices for the CCISS devices.

Expected results:
To include a patch to installation binary, to create the device mapper multipath devices for CCISS devices.

Comment 1 Senthil Kumar V 2009-06-11 06:57:02 UTC 
Is there any update on this issue?
Comment 2 Senthil Kumar V 2009-07-09 11:40:53 UTC 
Any updates on this? Has this been fixed in RHEL5.4 beta?
Comment 3 Ben Marzinski 2009-07-10 18:18:46 UTC 
Is the lack of cciss devices due to bz #484419?
Comment 4 Bryn M. Reeves 2009-07-10 18:35:06 UTC 
That's one of the blockers but there are probably other changes needed in mkinitrd and maybe anaconda (afaik cciss still needs a separate cciss_id WWID callout).
Comment 6 Ben Marzinski 2010-04-27 17:45:50 UTC 
the device-mapper-multipath package already provides a cciss_id callout.
/sbin/cciss_id.

Unless someone has a specific reason why we need this bugzilla, I'm going to close it as a dup of bz #484419.
Comment 7 Ben Marzinski 2010-05-12 17:58:02 UTC 
I'm closing this as a dup of 484419.  If there are specific device-mapper-multipath problems with cciss devices, feel free to reopen this bug with a comment explaining them.
