Description

This document contains information specific to the release of XCS 6.240 for the EVA4000/6000/8000

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

Fixes

The following issues have been resolved in XCS 6.240:

• Addressed issues where inquiries to the Storage Array Control Device (SACD) or LUN 0 caused

a controller termination or returned invalid formed responses.

• Fixed a controller termination (termination code 0x0c210106,

SCID_DRM_GSN_OUT_OF_SEQUENCE_12) that occurred due to instability and deadlock issues

with DR group copies.

• Addressed issues with inconsistent persistent reservation commands when the array power was

cycled or the controllers were shut down.

• Fixed a resource allocation issue that could result in stalled virtual disks, CSM resets, or controller

resets for "kill other" terminations.

• Modified the failed disk processing routine to prevent a deadlock situation that can occur when

a disk drive fails during a controller mastership transfer.

• Fixed a controller termination (termination code 0x02050100, Invalid Unit Cache State) that

occurred when deleting a presented snapshot LUN.

• Fixed an issue with DR groups not coming online when delays occur during a source-directed

controller failover on the destination array in HP Continuous Access EVA configurations.

• Added a recovery routine to reduce the interruption of data availability when a disk drive fails

to properly log into the arbitrated loop.

• Fixed a controller termination that occurred when Fibre Channel Echo ELS commands are

received from a Fibre Channel switch that has not completed fabric login with the array.

• Addressed an issue in the controller software that led to incorrect capacity reporting when

ungrouping and grouping drives.

• Fixed a Unit Stalled Too Long (USTL) condition that occurred when the DR group log became full

while the array was running with one active controller.

• Fixed a rescursive controller termination (termination code 0x0443011f) that could occur in an

asynchronous HP Continuous Access EVA configuration after multiple attempts to complete a copy

over slow links.
