[SunHELP] redhat 5 / emc disk ?

[listmail]

It's interesting to see something similar to your issue here 
https://www.redhat.com/archives/rhelv5-list/2009-January/msg00106.html 
about the 9 paths thing.  They also tried powerpath and got 9 paths as 
well so maybe it's more likely to be in the hba driver config or kernel 
settings?  I'm really not sure though without a box of my own to test 
with :)  Could be a multitude of things.  I actually understand the 
whole 'out of the box' preference but i'd still check what EMC certify 
would expect in case the answer is right there all along...  Good luck.

Same crowd complained when we (storage) told them they needed to keep the emc drivers updated on sparc boxes in production & development etc years ago. Not so much the worker bees as some management etc.
