Been seeing a lot of log entries for storage dropping and coming back online and was hoping to see if there is anything else I can try to look at.
Setup:
Dell M620 and M610 blades
2 x M8024 fabric switches connected to 2 x Cisco 3064E mid-tier switches for the storage network
1 software iSCSI adapter with 2 vmk's; the port groups have the other adapter listed as unused NOT standby
2 x Netapp FAS3240 in HA pair
Jumbo frames enabled
Round Robin with 10 IOPS for switch
Error:
Lost connectivity to storage device. . .few minutes later. . .Connectivity to storage device restored. . .
I verified jumbo frames aren't being dropped by doing a vmkping -s 8972 -d IP and it was successful. Looking through logs on the Netapp isn't showing anything abnormal performance or networking wise and it happens across both controllers (we have LUN's tied to single controllers for separation of data).
Any other recommendations on where I can check for problems would be much appreciated.
