Exadata Patching - Infiniband Switch

Here we have listed down bullet points to patch IB switches on Exadata Database Machine.

Syntax: #patchmgr -ibswitches [ibswitch_list_file] <-upgrade | -downgrade [-ibswitch_precheck] [-force]]


ibswitch_list_file contains IP of all the IB switches
Upgrade - to upgrade the switch
Downgrade - to downgrade the switch
ibswitch_precheck - to check the prerequisites

Patchmgr utility would be available in storage server patch directory.


#./patchmgr -ibswitches ibswitches -upgrade -ibswitch_precheck

How it works?
  • Disable Subnet Manager
  • Copy firmware to switch
  • Check minimal firmware version to upgrade it
  • Verify enough space in /tmp and /
  • Verify for free memory to start upgrade
  • Verify host details in /etc/hosts and /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth1
  • Verify for NTP server
  • Pre-upgrade validation
  • Start upgrade
  • Load firmware
  • Disable Subnet Manager
  • Verify that /conf/configvalid is set to 1
  • Set SMPriority to 5
  • Reboot switch
  • Restart Subnet Manager 
  • Start post-update validation
  • Confirmation: Inifiniband switch is at target patching level
  • Verifying host details in /etc/hosts and /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth1
  • Verifying NTP Server
  • Firmware verification on InfiniBand switch 
  • Post-check validation on IBSwitch 
  • Final Confirmation: Update switch to 2.1.3_4 (Firmware version)

Once it completes on one switch, it will start to upgrade next available switch and in last it will give overall status of upgrade.
