Hi ,
i have an 2 * IBM X3650 M4 servers with ESXi 5.5 OS both of them are connected to an HP NAS through iSCSI
One of these servers crashes periodically and displays a pink screen with exception 14 ,
IBM told me the following :
______________________________________________________________
you must add the following lines to the file /etc/multipath.confles
****************************************
blacklist {
device {
vendor "IBM"
product "ServeRAID M5110e"
}
}
****************************************
________________________________________________________
but no success the problem persists . in the addition to the fact the the problem exists only on one server.
I have these lines in vmkernel log ,

Do these lines mean that i have a problem in Raid controller??
Best Regards,
hi ,
i've upgraded the mega sas driver ,but i've received a pink screen again 
sorry for the delay of the feedback , client is not always available , the problem that this client has two servers with the same characteristics , but the second one, has no problem .
Best Regards ,
