EVA-CA VDISK increase in DR Group

[bachron]

What is the recomentation to increase the VDISK/DR Group from a CA Enviroment with Windows/Oracle
EVA has XCS 6.200
Is it like increase VDISK without Continuess Access or diff Step.

Referring to the Command View EVA Release note (Procedure for Expanding a DR group member):

The size of a DR group member (virtual disk) can be expanded whether the DR group is in synchronous or asynchronous mode. However, there are certain considerations for expansion in enhanced asynchronous mode (between arrays running controller software 6.0x or later).

If the virtual disk expanded while in enhanced asynchronous mode; the DR group log is not resized to reflect the expanded virtual disk. If the expansion is small, the log may be able to accommodate it. If the expansion is substantial, the log may not be large enough to handle it.

Resolution: Expand a DR group member as follows, only when the DR group is in synchronous mode:

Change the write mode from asynchronous to synchronous.

Complete the expansion of the DR group member.

If the maximum size of the DR group log was previously set , change the size of the log to accommodate the expanded DR group member. If the log size was previously determined by the controller software, no user action is necessary.

Change the write mode to asynchronous.

The DR group log size is adjusted to accommodate the expanded DR group member.
