AIX IBM Storage

Implementing iSCSI on AIX with Storwize V7000 (V7000U)

Introduction

When properly configured, an AIX server can act as :

  • iSCSI initiator : access storage devices using TCP/IP on Ethernet network adapters
  • iSCSI target : export local storage to be accessed by other iSCSI initiators using the iSCSI protocol

In our case, iSCSI initiator will be an AIX 7.1 (7100-00-03-1115) and the iSCSI target will be a Storwize V7000 Unified.

SVC + Storwize V7000 + Unified : 208 days reboot bug resolved with new firmware release (V6.3.0.2, V1.3.0.5)

A new firmware level has been released and corrects a serious bug :

  • Storwize V7000 and SVC : 6.3.0.2 (30 March 2012)
  • Storwize V7000 Unified : 1.3.0.5 (2 April 2012)

This strange bug due to a known Linux kernel issue  which result in a kernel panic (due to a internal counter overflow) after 208 days of uninterrupted time and reboot of both nodes was affecting SVC controller nodes, Storwize V7000,  and Storwize V7000 unified block node canisters.

This issue affects the following releases : 6.2.0.x (excepting V6.2.0.5), 6.3.0.x, 1.3.0.x (for unified)
