Cisco Prime Issue after Update

[gary_the_network_guy]

So I updated my Prime from 3.7 to 3.9, It was not an inline Upgrade. 

It was necessary to create a new Virtual Machine and restore the old system from a backup.

After restoring the backup I get this:

Warning: Unable to open /dev/sr0 read-write (Read-only file system.) /dev/sr0 has been opened read-only

Error: /dev/sr0: unrecognised disk label

does anybody know if that's something to worry about?

what backup application backup or appliance backup ? it should application back from PI 3.7 when you restoring on PI 3.9

check this thread :

I have done recently same process, it works (but its appliance - not VM)

[gary_the_network_guy]

It was an application update, so it runs just fine, I am experiencing no issues with the actual application itself.

I just restarted the VM when it hung up on me.

So maybe there is no issue at all.
