Summary of steps you should take to insure that you have a trouble free setup:
Make sure that you have unique names for all your LUN's. This is required if you have more than
one iSCSI unit or the additional LUN's will not be recognized by ESX.
For each LUN that you make, set the Maximum Connections field in Advanced Settings to the
total number of ESX servers that will be attached to the LUN. Example: For 5 servers, set
Maximum Connections to 5.
Make all of your arrays' LVM/LUN configurations in the TeraStation before attaching them to
your ESX server. Once they are made, you cannot change them due to a limitation in the
current firmware 1.32 / 1.40. Making a change after connecting to the ESX server requires
rebuilding the arrays and losing all data.
Our iSCSI units are best connected to your environment with only LAN 1 plugged into your
switch. Do not use LAN 2 as your only connection to the host server. Our units do not support a
network failover configuration.
Before making changes to your iSCSI TS's settings, first stop the iSCSI service in the TeraStation
Web Administrator interface. Do not stop the iSCSI service if the unit is actively being used with
your ESX server.
Change the time zone to your local zone.
