Important notes and workarounds

This section identifies important notes and workarounds for the EVA4x00/6x00/8x00 hardware and

XCS software.

Upgrading to XCS 6.220 puts asynchronous DR groups in Temp Sync state

Upgrading to XCS 6.220 from any version earlier than XCS 6.200 puts asynchronous DR groups in

Temp Sync state.

The XCS 6.xxx controller software has a Temp Sync state for DR groups that is used when a full copy

is required. If the DR groups require a full copy when you initiate a controller software upgrade, the

DR groups will move to the Temp Sync state upon completion of the upgrade and the full copy. You

must reset the asynchronous mode for these DR groups, using HP Command View EVA or an equivalent

command, to return to normal operations.

HP recommends that you ensure the DR groups are not in a full copy state before upgrading to XCS

6.220.

Changing the host port topology

Before changing the topology settings of an array host port, physically disconnect the host port from

its existing connection, change the topology setting, and then reconnect the host port.

For example, to change from a fabric (switched) topology to a direct connect topology, do the

following:

1. Disconnect the host port(s) from the Fibre Channel switch.

2. Using the operator control panel (OCP), change the controller host port mode from fabric to direct

connect.
