Veritas Access Appliance 8.2 Solutions Guide for NetBackup

To configure an IRE

1. If A.I.R. is not configured on the production domain, continue to the next step.

   If A.I.R. is already configured on the production domain, log in as a local user with administrator role (same user that was used for Access Appliance CLISH login). Run the following command to show the SLP windows for replication 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 the 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

   The following is an example output of the command:

   EveryDayAtNoon:
   SLPs: SLP1
   Sunday start: 12:00:00 duration: 00:59:59
   Monday start: 12:00:00 duration: 00:59:59
   Tuesday start: 12:00:00 duration: 00:59:59
   Wednesday start: 12:00:00 duration: 00:59:59
   Thursday start: 12:00:00 duration: 00:59:59
   Friday start: 12:00:00 duration: 00:59:59
   Saturday start: 12:00:00 duration: 00:59:59
   
   WeeklyWindow:
   SLPs: SLP2
   Sunday start: 10:00:00 duration: 01:59:59
   Monday NONE
   Tuesday NONE
   Wednesday NONE
   Thursday NONE
   Friday NONE
   Saturday start: 10:00:00 duration: 01:59:59

   This example shows two SLP windows:

   • A daily window for one hour starting at noon.

   • A weekly window for two hours starting at 10:00 A.M.

2. Based on the requirements for your environment, determine a schedule and take note of it. For an existing A.I.R. environment, the schedule must accommodate the SLP windows that you viewed in the previous step.

   You can set a daily schedule that is open at the same time each day, or you can set a different schedule for each day of the week.

   In the previous example, you can accommodate both SLP windows with either of the following:

   • A daily schedule from 10:00 A.M. to 1:00 P.M.

   • A schedule from 12:00 P.M. to 1:00 P.M. on Monday through Friday and a schedule from 10:00 A.M. to 1:00 P.M. on Saturday and Sunday

   Note:

   If the production environment and the IRE are in different time zones, the schedule must begin only once per day in both time zones. For example, if one environment is in the Asia/Kolkata time zone and the other is in the America/New_York time zone, the following schedule in Kolkata is not supported: Tuesday start time 22:00:00 and Wednesday start time 03:00:00. When these start times get converted to the New York time zone, they become Tuesday start time 12:30:00 and Tuesday start time 17:30:00, which is not supported.

3. Run the following command to configure which subnets and IP addresses are allowed to access the storage server:

   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.

4. Run the following command to set the daily air gap schedule:

   setting ire-network-control set-schedule start_time=<time> duration=<duration> [weekday=<0-6>]

   Where [weekday=<0-6>] is an optional parameter to indicate the day if you need to set different schedules for different days. 0 is Sunday, 1 is Monday, etc.

   For example:

   setting ire-network-control set-schedule start_time=10:00:00 duration=03:00:00 weekday=0

5. Before you can send data between the production domain and the IRE storage server, you must add MSDP reverse connections and add the replication operation.
