Review StorageArrayProfile.txt and Make Sure All Is Optimal Except for the Channel

Run the following two commands from the Storage Manager Command Line Interface (SMcli):

smcli -n <storage-name> -p password -c "clear allPhysicalDiskChannels stats;"

 

smcli -n <storage-name> -p password -c "set physicalDiskChannel [2] status=optimal;"

 

The above command makes channel 2 optimal.

No reboot is required.

 

	Note:
	On the system that has MDSM Client installed run cmd then CD into C:\Program Files (If your running it on 64 bit) or then CD into C:\Program Files\Dell\MD Storage Software\MD Storage Manager\client\ There you will see smcli.exe MDSM Client can be installed from the MD3xxx resource CD.
