Managing an isolated recovery environment on a storage server

Once you have configured an isolated recovery environment (IRE) on a storage server, you can manage it from the MSDP restricted shell with a local user with administrator role (same user that was used for Access Appliance CLISH login). Use the following commands.

To view the SLP windows from the primary server to the server:
setting ire-network-control show-slp-windows production_primary_server=<production domain> production_primary_server_username=<production username> ire_primary_server=<IRE domain> ire_primary_server_username=<IRE username>
Where:
- <production domain> is the fully qualified domain name (FQDN) of the primary server in your production environment.
- <production username> is the username of a NetBackup primary user with permission to list SLPs and SLP windows in the production environment. For Windows users, enter the username in the format <domain name>\<username>. For other users, enter the username only.
- <IRE domain> is the FQDN of the primary server in the IRE. Use the same hostname that you used for the target primary server when you configured the SLPs in the production environment.
- <IRE username> is the username of a IRE NetBackup primary user with permission to list SLPs and storage units in the IRE. For Windows users, enter the username in the format <domain name>\<username>. For other users, enter the username only.
For example:
production_primary_server=examplePrimary.domain.com production_primary_server_username=example_user ire_primary_server=exampleIREPrimary.domain.com ire_primary_server_username=example_user1
Note:
The SLP replication window on the production domain must be configured to be open at the same time as the IRE schedule.
To list the MSDP reverse connections:
setting ire-network-control list-reverse-connections
To add an MSDP reverse connection:
setting ire-network-control add-reverse-connection remote_storage_server=<production MSDP server> [remote_primary_server=<production primary server>] [local_storage_server=<IRE network interface>]
Where:
- <production MSDP server> is the FQDN of the MSDP server in your production environment.
- [remote_primary_server=<production primary server>] is an optional parameter for the FQDN of the primary server in your production environment. This parameter is required if the IRE domain uses an alternative name to access the production primary server. This scenario usually occurs if the production primary server runs on multiple networks with multiple hostnames.
- [local_storage_server=<IRE network interface>] is an optional parameter for the hostname of the network interface to use for image replication on the IRE storage server. This parameter is required if the network interface for replication is different than the IRE storage server name.
To verify that a reverse connection works:
setting ire-network-control validate-reverse-connection remote_storage_server=<production MSDP server> [remote_primary_server=<production primary server>] [local_storage_server=<IRE network interface>]
To remove an MSDP reverse connection:
setting ire-network-control remove-reverse-connection remote_storage_server=<production MSDP server>
To view the allowed IP addresses and subnets:
setting ire-network-control show-allows
To add IP addresses and subnets to the allowed list:
setting ire-network-control allow-subnets subnets=<CIDR subnets or IP addresses>
Where <CIDR subnets or IP addresses> is a comma-separated list of the allowed IP addresses and subnets, in CIDR notation.
For example:
setting ire-network-control allow-subnets subnets=10.80.120.208,10.84.48.0/20
Note:
The IRE primary server, the IRE media servers, and the DNS server for the IRE must be included in the allowed list. If all of these servers are in the same subnet, only the subnet is required to be in the allowed list.
To remove the IP addresses and subnets from the allowed list:
setting ire-network-control allow-subnets subnets=,
To view the daily air gap schedule:
setting ire-network-control show-schedule
To change the air gap schedule:
setting ire-network-control set-schedule start_time=<time> duration=<duration>
For example:
setting ire-network-control set-schedule start_time=10:00:00 duration=03:00:00
To stop the air gap schedule:
setting ire-network-control delete-schedule
To view the current network status and check whether the external network is open or closed:
setting ire-network-control external-network-status
To manually open the external network:
setting ire-network-control external-network-open
To manually close the external network and resume the air gap schedule:
setting ire-network-control resume-schedule

Note:

The commands may take a few minutes to take effect.
