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]]
Here
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.
Patching
#./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.
