  • Support for SLES 10 SP4

Tested OS

  • AIX 6.1.8 and 7.1.2
  • Rhel5,6 SLES 10,11

Key Bug fixes

  • A couple IPMI bugs existed in 2.7.5:

    • In an initial install of 2.7.5 on new hardware, rvitals and rinv would not work.
    • For cmds like rvitals for a lot of nodes would give errors like: node1: Error: 1 code on opening RMCP+ session

    Both of the problems are fixed in this release, see bug 3156.

Restrictions and Known Problems

  • On Linux, if after upgrade and you run lsxcatd -a, it does not show you are running Version 2.7.6, then you will need to do the following:
    • service xcatd stop
    • ps -ef | grep xcatd, kill -9 any processes
    • service xcatd start
    • lsxcatd -a to check
    • This will be fixed in 2.7.7 with the following defect: bug 2359
