In my home lab I’m using Lenovo M900 tiny to run ESX 6.0 and using Synology DS1813+ to provide the ISCSI LUN.
And I’m using VCSA as my vCenter server and put it on the iSCSI lun.
Today I updated my DS1813+ to DSM 6.0 update 1, during the update, I reboot my synology nas. And it seems ESX lost connecting to the iSCSI LUN and my VCSA was dead.
It seems that the volumes are in read-only and the shell is dead.
Don’t worry, let’s fix it.
Please follow below steps:
- stop VCSA machine
- add the iso of RHEL7 installation CD to the (actually as CD/DVD of the machine and modified boot order to start from the CD
- boot from CD
- enter shell of LiveCD
- issue the following commands (to see that logical volumes are OK)
pvscan lvscan fsck -fvy /dev/log_vg/log
- repeat step 5 to check all the volumes
After finished, remove the ISO and reboot the VM.
You will find VCSA is back:)
