Edit the VRA to change the connection method (VIB or password), host password, VRA bandwidth group, or network settings for a VRA, for example when the gateway to the VRA is changed.

1.To edit the VRA, in the Zerto User Interface click SETUP > VRAs.
2.Select the VRA to edit, and click Actions > Edit.

The Edit VRA dialog is displayed.

3.Edit the Host Root Password if the password for the host has changed. To display the password in plain text, select Show password.
4.Edit the VRA Bandwidth Group from the drop-down list.
To create a new VRA Bandwidth Group, enter the name of the new group and click CREATE. You can then select the new group from the drop-down list.
5.Edit VRA RAM.

The amount of memory to allocate to the VRA.

Default is 3.

The amount determines the maximum buffer size for the VRA for buffering IOs written by the protected virtual machines, before the writes are sent over the network to the recovery VRA.

The recovery VRA also buffers the incoming IOs until they are written to the journal.

If a buffer becomes full, a Bitmap Sync is performed after space is freed up in the buffer.

For details, refer to Zerto Scale and Benchmarking Guidelines.

6.Edit VRA vCPUs .

The number of vCPUs to allocate to the VRA.

Default is 1. Maximum is 4.

Increasing the number of vCPUs to two is recommended if the VRA is used for Long-term Retention, or for high loads.
Increasing the number of vCPUs to more than two should only be per Zerto Support recommendation.

AdmonitionNote: If the VRA RAM or VRA vCPU is changed, upon saving the new configuration, a message will appear to inform you that the VRA will power off to complete the requested update.

7.Edit the VRA Network Details as follows:
Configuration: Either have the IP address allocated via a Static IP address or a DHCP server.

AdmonitionNote: Zerto strongly recommends using only Static IPs on the production site.
During trials you may use either static IPs or DHCP.
The reason for this is that if the VRA IP is allocated via DHCP and the DHCP server at a later date allocates a different IP, ZVM does not change the VRA IP in the ZVM records.

If you select Static, you must also enter the following:
Address: The IP address for the VRA.
Subnet Mask: The subnet mask for the network. The default value is 255.255.255.0.
Default Gateway: The default gateway for the network.
8.Click Save.

The following folder is created as part of the VRA installation and must not be removed:

C:\zerto-temp-<storage_name> – VRA installation files.

Where <storage_name> signifies the target host.

When a VRA is installed using the local storage (C:\), there is only one folder with this name.
When a VRA is installed on remote storage, a second folder with the same name is also created where the VRA is installed.
