Configure the vSAN IO timeout settings.

esxcfg-advcfg -s 100000 /LSOM/diskIoTimeout

esxcfg-advcfg -s 4 /LSOM/diskIoRetryFactor

Notes:

• This is not required if you are running ESXI 6.0 patch ESXi600-201608001 or later.
• These commands must be run on each ESXi host in the vSAN cluster.
• These commands are effective immediately. No reboot is required.
• These commands result in persistent changes and remains configured across reboots.
