VCS VM Factory Reset

[Justin Ferello]

Hey all,

We purchased a bunch of VM VCSes for our lab.  I just set one up and configured for a test in my lab.  I got it all activated and license keys loaded.  Once I was done the test I went to do a factory reset to get it back to default for the next person, however the factory reset fails on looking for the default image.  How can I fix this?  Also will doing a factory reset change the S/N?

         

Thank you,

Hi Justin,

in order to reduce the size of the VM VCS .OVA file, the VM VCS does not come with a default factory reset image installed.

For doing a factory reset on VM VCS, you should SCP a standard software image to the VM VCS, to folder /mnt/harddisk/factory-reset, and save the software image as 'tandberg-image.tar.gz', as this is the file name which the factory reset script will be looking for.

You could for instance download the X7.2 VCS software from Cisco.com, rename that file to 'tandberg-image.tar.gz' and upload this to '/mnt/harddisk/factory-reset' on your VM VCS and you should be good to go

Andreas,

Worked like a charm, thank you!  You only forgot one major step, you also need to create a file in the same directory called rk with the release key for that VCS in the file.

Great solution is started me off the right place.  Just in case you need to perform the factory reset from the console login and using a USB drive with the file (tandberg-image.tar.gz - which you renamed after downloading from Cisco).

Plug in the USB drive - look for the sdb data first it will look something like this:

scsi 7:0:0:0: Direct-Access Generic Flash Disk 8.07 PQ: 0 ANSI: 4
sd 7:0:0:0: Attached scsi generic sg1 type 0
sd 7:0:0:0: [sdb] 61440000 512-byte logical blocks: (31.5 GB/29.3 GiB)
sd 7:0:0:0: [sdb] Write Protect is off
sd 7:0:0:0: [sdb] Write cache: disabled, read cache: enabled, doesn't support DPO or FUA
sdb: sdb1
sd 7:0:0:0: [sdb] Attached SCSI removable disk

Now that you know the sdb get the full name type in mount

it will look like   /dev/sdb

Then get the partition of the drive

fdisk -l

It will look something like /dev/sdb1

Next mount the drive to a place where you can create a directory (only place is in /mnt/harddisk/factory-reset/

create a directory there called mkdir media

then mount your usb drive to the media directory  mount /dev/sdb1 /mnt/harddisk/factory-reset/media

if you go to /mnt/harddisk/factory-reset/media and then use ls -l to list the files you will see your file

Use cp to copy the file from the media directory to the factory-reset directory.

Hi Justin!

How are you?

First of all I would recommend to take a vmware snapshot, so you can revert to the previous / known state.

Thats a quite handy feature which you, especially want to use in a lab or before you do an upgrade! :-)

For more info about snapshots you should check out the vmware documentation.

The admin guide for the conductor mentions systemreset.sh, which I successfully used on a virtualized

conductor and it also seems to work for me on a virtual vcs when I just tried it (after taking a shapshot :-)

but it wipes out the complete config incl the keys, so its a bit less convenient.
