I received the below error codes relating to external storage (DS4700) behind the VSP.
The connections go via a switch.
RefCode : 21d24d
RefCode : 21d255
RefCode : 21d20d
RefCode : 21d215
All relating to the same detail below:
Detail : Threshold over by external storage system connection path response time-out
Then this one:
RefCode : 21d04d
Detail : External storage system connection path blocking
I don't see any errors on the switch.
The external path has timeout values set as follow:
I/O Timeout 15 sec
Path Blockade Watch 10 sec
The only current error on the DS4700 is a disk failure which has iniated a hot spare.
Should I be concerned about this as the current path group show up as Warning?
What is the recommended timeout values?
