Hi,

 

I have a problem in my environment in which the disks goes and comes for fractions of seconds.

Storage is VSP , mainly VMs and AIX hosts are affected, for which we get alerts everytime it happens.

Servers are having connectivity with Cisco MDS 9513 director Switches.

 

Also , I have checked the loggs for the individual switch ports and i have found that the frames are discarded on most of the ports. Can it be the reason.

 

Regards

Prakhar
