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.
Fixes The following issues have been resolved in XCS 6.220: • • • • • • • • • • • • • • Resolved an issue in which the controller blowers failed within a short span of time. The battery test algorithm has been improved. SCSI support for the “Set Peripheral Device” identifier has been implemented. The algorithm for handling SCSI inquiry timeouts caused by failing disk drives has been enhanced. Event reporting no longer incorrectly logs events pertaining to unsupported drive firmware.
Online controller firmware upgrade note HP StorageWorks Engineering has determined that Enterprise Virtual Arrays which are configured with large amounts of mapped virtual disk capacity may exceed 60 seconds when the restart of the controllers occurs after a firmware upgrade. During this extended restart time, the array is not processing server data and this may lead to file system timeouts. Mapped virtual disk capacity is the sum of all virtual disks, snapshots, and mirrorclones on the array.
Click Storage Networking under Storage, and then select HP StorageWorks SAN under HP StorageWorks SAN Solutions. Supported Fibre Channel switches For complete information on which Fibre Channel switches are supported on XCS 6.100 or later, see the HP StorageWorks SAN design reference guide, which can be downloaded from the following website: http://www.hp.com/support/manuals Click Storage Networking under Storage, and then select HP StorageWorks SAN under HP StorageWorks SAN Solutions.
3. Connect the host HBA(s) directly to the array host port(s). Host port connection limit on B-series 3200 and 3800 switches The B-series 3200 and 3800 switches are limited to a maximum of three EVA4x00/6x00/8x00 host ports on a single B-series 3200 and 3800 switch running version 3.2.x. HP recommends not exceeding more than one storage host port connection on a single switch.
• You can bypass this issue by setting the load balancing policy for each LUN to NLB using the MPIO DSM CLI. Microsoft is currently working on a resolution to address this issue. C-series switch settings for XCS 6.100 or later If C-series switches are not set correctly, the EVA host ports may not log back in to the fabric after changes occur in the fabric. This issue involves the following C-series switch model families: 90xx, 91xx, 92xx, and 95xx.
4. Click Restart. The controller is restarted. At the conclusion of the restart the host port should be operating normally. C-Series MDS 9020 switch and HP Continuous Access EVA The C-Series MDS 9020 switch is only supported with HP Continuous Access EVA when the EVA is running XCS 6.000 or later. Microsoft Windows MPIO DSM 3.00.00 is recommended HP recommends that you upgrade to Windows MPIO DSM (Device Specific Module) version 3.00.00 or later, which provides the read optimization feature, for XCS 6.
