Applying security patches in the
Cyber Recovery vault
Move patch software from your production system into the
Cyber Recovery vault securely. Then apply software patches to update the
Cyber Recovery management host and
DD systems, as well as applications such as NetWorker, Avamar,
PowerProtect Data Manager, CyberSense, and so on.
Prerequisites
On the production
DD system, create a dedicated
MTree.
On the production and
Cyber Recovery vaultDD systems, create and initialize a
DD replication.
On the
Cyber Recovery system, create a
Cyber Recovery policy and select the replication context that is associated with the patch software.
Optionally, for a
Cyber Recovery virtual appliance, back up data on and take a VM snapshot of the
Cyber Recovery virtual appliance. Then, save the backup data and snapshot outside of the
Cyber Recovery virtual appliance.
About this task
To update vault components, follow these steps if you do not have physical access to the physical
Cyber Recovery vault or do not want to take a laptop or external storage into the physical
Cyber Recovery vault.
NOTE:
These steps describe how to apply a software patch to the
Cyber Recovery host. Use these steps to apply a software patch to other systems in the
Cyber Recovery vault.
Ensure that you reboot the virtual appliance after you complete the following steps.
Steps
Go to
Dell Online Support to obtain the
cyber-recovery-osupdate-<current release>.bin file.
In the production environment, place the patch software on a host.
On the production
DD system, export the dedicated
MTree to that host.
From that host, NFS mount the production
MTree.
Download the patch software to the NFS location from that host.
Perform a checksum and run a scanner to ensure that the downloaded patch software is uncorrupted.
Optionally, test the software update on a test system.
On the
Cyber Recovery system, perform a Sync Copy operation to replicate the
MTree on which the patch software resides.
After the Sync Copy job completes, create a
Cyber Recovery sandbox of the copy and export it to the host on which you want to access the patch software.
Optionally, do either of the following:
Run a scanner to ensure that the downloaded copy of the software patch is uncorrupted.
Perform an analysis by using the
CyberSense.
From the
CRCLI, run the
crsetup.sh --save command to create a backup copy.
Copy the software patch to the
Cyber Recovery management host to a directory of your choice.
From the CLI, run the following command:
# ./cyber-recovery-osupdate-<current release>.bin
For the
Cyber Recovery virtual appliance, reboot the virtual appliance.
NOTE: You must reboot the virtual appliance, otherwise, you might encounter problems.
