8x00 Enterprise Virtual Array release notes (XCS 6.220) (5697-8035, April 2009)

Version: XCS 6.220

Description

This document contains information specific to the release of XCS 6.220 for the EVA4000/6000/8000

and EVA4100/6100/8100. Much of the information included here is not documented elsewhere,

so it is recommended that you read this information thoroughly before installing and operating the

EVA4x00/6x00/8x00.

NOTE:

If you are using asynchronous replication, HP strongly recommends that you upgrade to XCS 6.200

or later to ensure maximum performance.

Update recommendation: Recommended

Product models

These arrays are referenced as EVA4x00/6x00/8x00 throughout the document.

Enhancements

XCS 6.220 provides the following enhancements:

• EVA management software support. HP Command View EVA 8.0.2 is required with XCS 6.220.

HP Command View EVA 9.0 is supported with XCS 6.220.

• Connectivity support. Support for VMWare ESX 3.0.3, 3.5.1, 3.5.2, 3.5.3 and HP Tru64 UNIX

Alpha 5.1B-5 are added.

• HP Continuous Access EVA persistent bitmap. The bitmap used to enable a fast copy after a log

full condition is now persisted, ensuring that a fast copy can be performed even after a controller

resynchronizes or reboots.

NOTE:

The DR group state does not reflect a fast copy or a full copy. To make this distinction, you must

look at the controller event log after the copy completes. The firmware does not send an event

notification indicating that a fast sync version of copy is being used.

• HP Continuous Access EVA fast copy after instant restore. For remote replication, the controller

software performs a fast copy of the restored source volume instead of a full copy. This reduces

the amount of copy I/O required to re-normalize the target volume.
