[ewg] ***SPAM*** Info:emcp:Received remove upcall for index 0x3 devno 0x800030

2008-11-25 Thread Gnanasekar Loganathan 
Hi All,
Setup details:

Storage: Clariion
Switch: SFS 3012
Host: rhel5
S/w: OFED-1.3.1 and emc power path

After i restarted the switch, i'm getting the Info:emcp:Received remove
upcall for index 0x3 devno 0x800030 message, my server goes to hang.

May i know the reason?

Is any body came across this kind of error?



Thanks,
Gnana

[ewg] [PATCH] IB/ehca: Change misleading error message

2008-11-25 Thread Joachim Fenkes 
The error message printed when the eHCA driver prevents memory hotplug is
misleading -- the user might think that hot-removing the lhca, hotplugging
memory, then hot-adding the lhca again will work, but it doesn't.

That's too bad... I applied this patch but out of curiousity, why
doesn't the hot-remove/hot-add work?  I would have thought that
re-registering all of memory after the hot-add would do the right thing.
