ESXI Patching and Upgrade
-
ISO image process:
-
Download ISO from VMware support portal, and upload it to VCenter in Update manager tab.
-
Process: Import iso – select downloaded ISO and create baseline.
-
Post base line created put host in MM by checking cluster CPU and Memory usage of cluster .
-
After host in MM will go to updates tab on ESXi and attach baseline what we created, next check for compliance if we don’t see any compliance issue we can go and remediate the host .
-
At 48 percent host will get rebooted and upgrade or patch will be applied .
-
As per validation we will check network adapters and storage adapter are connected to ESXi in proper way or not .
-
Offline Bundle:
-
Take the offline bundle and copy to Datastore where esxi has access .
-
Enable SSH and take putty – run this command
-
ESXCLI software vib install / update –d “/path of offline bundle “
-
Reboot the esxi to apply patch or upgrade.
-
As per validation we will check network adapters and storage adapter are connected to ESXi in proper way or not .
-
If ESXI upgrade or patch fail to update how you will roll-back.
-
Login into hardware, while ESXI is booting Shift + r , if will show us previous version we can select and complete roll back . Video Roll back : https://www.youtube.com/watch?v=HFntfkAl9n4
-
As per validation we will check network adapters and storage adapter are connected to ESXi in proper way or not .
-
After esxi upgrade or patching do you face any issues :
-
We have couple of issue like Storage adapters are not working as expected , HA agent is fail to install , SNMP service is fail to start .
-
Storage adapter : Take putty of esxi and run command to reset HBA adapter .
-
HA agent : we found there is no space available in esxi to install agent so we have delete unwanted failed and re installed HA agent .
-
SNMP is fail to start : Will take SNMP config file from working server and paste in non working sever that will fix the issue .
