RHBA-2011:0745 - fence-agents bug fix and enhancement update

Synopsis

fence-agents bug fix and enhancement update

Type/Severity

Bug Fix Advisory (none)

Topic

An updated fence-agents package that fixes bugs, adds support for new hardware and Red Hat Enterprise Virtualization is now available.

Description

Red Hat fence agents are a collection of scripts to handle remote power management for several devices. They allow failed or unreachable nodes to be forcibly restarted and removed from the cluster.

This update includes the following bug fixes:

  • Metadata generation has been corrected in order to provide information for all known parameters for each fencing agent. (BZ#618703, BZ#623266)

  • Port is now a synonym of module_name for fence_drac5, making it consistent with other fencing agents. (BZ#619096)

  • Information on how to use fence_ipmi with HP iLO version 3 has been added to the manual page. (BZ#648892)

  • The fence_egenera manual page has been improved. (BZ#635824)

  • fence_scsi now works when devices report "Unit Attention". (BZ#640343)

  • fence_scsi now verifies action results. (BZ#644385)

  • fence_scsi now correctly identifies device mapper multipath devices. (BZ#644389)

  • fence_scsi pattern matching has been improved. (BZ#670910)

  • fence_scsi now logs errors whenever a command fails. (BZ#672597)

This update adds the following enhancements:

  • Support for Cisco UCS blade systems is now provided. (BZ#580492, BZ#678904)

  • It is now possible for one node to delay fencing in a two-node cluster. (BZ#614046)

  • Fence_ipmilan can now use the "diag" option. (BZ#655764)

  • The package has been updated to provide a fencing agent that is able to communicate with Red Hat Enterprise Virtualization Manager, allowing virtual machines to be fenced. (BZ#595383)

  • For Intelligent Platform Management Interface (IPMI) devices, the "power_wait" delay can now be adjusted in order to support newer iLO 3 firmware. (BZ#642671)

  • Brocade 200E, Brocade 300, Brocade 4100, Brocade 4900, and Brocade 5100 fencing devices are now supported by the fence_brocade agent, and can be used with both Red Hat High Availability and Red Hat Resilient Storage. (BZ#642235, BZ#680170)

  • An issue with fence_scsi where the key was erroneously reported as 0 has been addressed. (BZ#653504)

  • fence_wti now correctly handles large (>20) port switches. (BZ#678522)

  • fence_rhevm has been updated to the current RHEVM development API. (BZ#681669, BZ#681674)

  • fence_cisco_ucs was missing from the fence-agents package, but is now included. (BZ#682715)

All users requiring any of the changes noted above should upgrade to this new package, which fixes these issues and adds these enhancements.
