MD3000i and Modular Disk Storage Manager
Howdy Folks,
We have a brand new MD3000i iSCSI array. There are 4 servers connected to the array, via iSCSI, on a separate Cisco 3750 switch. The array management interfaces are on our production network. The configuration has been pretty simple, but I keep running into problems with the Modular Disk Storage Manager (MDSM).
After using the MDSM for a few days, it looses the connection to the storage modules on the MD3000i. I can still ping the management and iSCSI interfaces of the array and iSCSI still works flawlessly from the servers, but I can't manage the array at all.
The MDSM says the storage array is currently unresponsive. Removing the array and trying to add it back doesn't work. I have to physically power down the array to start managing it again.
I have checked all the ports for duplex/speed mis-matches on the network switches, but don't see any problems.
Any suggestions?
