Important notes and workarounds This section identifies important notes and workarounds for the EVA4x00/6x00/8x00 hardware and XCS software. Upgrading to XCS 6.240 puts asynchronous DR groups in Temp Sync state Upgrading to XCS 6.240 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 6.240. Default log file size changed in asynchronous replication mode For XCS 6.200 or later, with asynchronous replication mode, if you do not specify the replication write history log maximum size, the firmware sets the log size to 100 GB by default. If 100 GB VRAID1 space is not available, the following error message: "Invalid async log size" will be reported. To resolve this issue, do one of the following: • Set the log size between 1.6 GB and 2 TB • Free some space available in the disk group • Select a different disk group for placement of the log which has adequate available space HP MPIO EVA DSM requirement HP recommends that you always install the latest version of HP MPIO EVA DSM, which you can download from: http://www.hp.com/support/downloads 1.

Important notes and workarounds
This section identifies important notes and workarounds for the EVA4x00/6x00/8x00 hardware and
XCS software.
Upgrading to XCS 6.240 puts asynchronous DR groups in Temp Sync state
Upgrading to XCS 6.240 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
6.240.
Default log file size changed in asynchronous replication mode
For XCS 6.200 or later, with asynchronous replication mode, if you do not specify the replication
write history log maximum size, the firmware sets the log size to 100 GB by default. If 100 GB VRAID1
space is not available, the following error message: "
Invalid async log size
" will be reported.
To resolve this issue, do one of the following:
•
Set the log size between 1.6 GB and 2 TB
•
Free some space available in the disk group
•
Select a different disk group for placement of the log which has adequate available space
