Hello,
The VSC appliance was most likely named SVC since there is another appliance for the "VSC, VASA Provider and SRA virtual appliance " which most likely has the name of vsc as VM.
You can change the name but you will need to make sure it is reflected within your dns as well.
I was able to rename the appliance by login in using the maint user.
Once login choose option 4 followed by option 2
At the prompt you will perform the below:
1. verify the hostname
diag@vsc1:: hostname
vsc1
diag@vsc1:: sudo hostname svc1
diag@vsc1:: sudo vi /etc/hostname
{edit the name and change it to svc1}
Once above complete, you will need to reboot the VM.
To rename the VM within vsphere, click Edit and go to settings and you can just change the name under General settings tab.
Thanks
