IP Changes Not Honored

When Windows reaches the maximum limit of iSCSI connections, it does not honor changes in IP inclusion and exclusion. For example:

• If a Windows host has 4 NICs and there are 40 volumes spanned across three arrays, 4 NICs times 3 arrays results in 12 connections for each volume.
• But the upper limit is 8 connections per volume. Therefore, each volume makes 8 connections.
• Eight volume connections times 40 volumes results in a total of 320 connections on the Windows host.
• But Windows has a maximum limit of 255 connections. Therefore, the server makes only 255 connections.

At the maximum limit of 255 iSCSI connections, the Windows host and the HPE Storage Connection Service do not honor changes in IP inclusion and exclusion. To make changes, you must first reduce the number of iSCSI connections below the maximum.
