To create a NetBackup media server instance

1. Make sure that the NetBackup media server application you want to use is located in the repository on the Flex Appliance Console.
2. Perform the following tasks if you have not already:

   • Configure at least one network interface. You can configure a physical interface, add a VLAN tag, or create a bond.

   • Add at least one tenant.

3. Gather the following information for the new instance:

   Note:

   The hostname and IP address must not be in use anywhere else in your domain.

   • Tenant that you want to assign it to

   • Hostname (maximum of 63 characters including the domain name)

   • IP address

   • Network interface

   • Domain name

   • Name servers

   • Search domains

   • Primary server hostname

     Note:

     The Flex Appliance Console does not prevent entering the same hostname in both the Hostname for NetBackup Media Server and the Primary server hostname fields, but that configuration is not supported. You must have a preexisting primary server with a different hostname.

   • Certificate Authority (CA) information for one of the following:

     For a NetBackup CA:

     • CA SHA-1 or SHA-256 certificate fingerprint

       If the primary server is a Flex instance, you can locate this information from the instance details page of the primary server instance. Click on the instance name under Application instances on the System topology page.

       If the primary server is not a Flex instance, see the NetBackup Security and Encryption Guide for the steps to locate this information from NetBackup.

     • (Optional) Token for host ID-based certificate

       Depending on the primary server security level, the host may require an authorization or a reissue token. If you do not specify a token when you create the instance, the wizard attempts to automatically obtain the certificate.

     For an external CA:

     • Trust store, in PEM format

     • Host certificate, in PEM format

     • Private key, in PEM format

     • (Optional) Passphrase of the private key

       A passphrase is required if the key is encrypted.

     • (Optional) Custom CRL files

   • (Optional) Password for host name-based certificate

     A host name-based certificate is mandatory if Enhanced Auditing is enabled on the primary server. You can specify the password when you create the instance, or you can deploy the certificate from the primary server later.

4. Add the hostname for the new instance to the Media servers list or the Additional servers list on the primary server, as follows:

   • Sign in to the NetBackup web UI. On the left, click Hosts > Host properties.

   • Select Primary server from the list.

   • If necessary, click Connect.

   • Click Edit primary server.

   • Click one of the following:

     • If you want MSDP storage on the instance, click Servers. Then click the Additional servers tab.

     • If you want AdvancedDisk storage on the instance, click Servers. Then click the Media servers tab.

   • Click Add and enter the host name for the new instance. The host name should appear in the list.

   • Click Save.

5. If a firewall exists between the primary server and the new instance, open the following ports on the primary server to allow communication:

   • vnetd: 13724

   • bprd: 13720

   • PBX: 1556

   • If the primary server is a NetBackup appliance that uses TCP, open the following ports:

     443, 5900, and 7578.

6. From the System topology page of the Flex Appliance Console, navigate to the Application instances section.
   
7. Click Create instance.
8. Select the appropriate media server application from the repository list that appears, making sure to verify the version number. Click Next.
9. Follow the prompts to create the instance. When you are done, you can view the progress in the Activity Monitor, which is accessible from the left pane of the Flex Appliance Console.

   Note:

   If you use DNS and the DNS server includes both IPv4 and IPv6 addresses, the instance must be configured with both as well.

   If you do not want to use DNS or want to bypass DNS for certain hosts, verify that the hostname resolution information is included in the Hosts file entries field. You must include entries for the primary server and any other NetBackup hosts that you want to communicate with the instance.

10. Once the instance has been created successfully, you must change the password from the known default password. To change the password, open an SSH session to the instance and log in with the following credentials:

    • Username: appadmin

    • Password: P@ssw0rd

    Follow the prompt to enter a new password. When the password change is complete, you are logged out. You can log back in with the new password.

11. Create the storage servers for your selected storage, as follows:

    • Sign in to the NetBackup web UI. On the left, click Storage > Disk storage. Navigate to the Storage servers tab and then click Add.

    • In the Storage type list, select Disk storage servers.

    • From the Category options, select AdvancedDisk or Media Server Deduplication Pool (MSDP, MSDP Cloud) and follow the prompts to create the storage servers. Enter the following storage information for AdvancedDisk and MSDP:

      • AdvancedDisk storage volume: /mnt/advanceddisk/vol*

      • MSDP storage path: /mnt/msdp/vol0

        Note:

        If the MSDP disk pool spans multiple volumes, only select vol0. Also note that the wizard shows only a portion of the storage, but the remaining storage displays after the storage server is configured.

    See the following guides for more information on NetBackup storage configuration:

    • The NetBackup AdvancedDisk Storage Solutions Guide

    • The NetBackup Deduplication Guide

12. (Optional) If you need to upload custom CRL files for an external CA, perform the following steps:

    • Run the following command on the instance to create a directory for the files:

      sudo mkdir -p /mnt/nbdata/hostcert/crl/

    • Use an SCP tool to copy the files to the new /mnt/nbdata/hostcert/crl/ directory.

    • Run the following commands on the instance to enable the CRL check using the custom files:

      sudo nbsetconfig ECA_CRL_CHECK = CHAIN

      sudo nbsetconfig ECA_CRL_PATH = /mnt/nbdata/hostcert/crl/

    See the NetBackup Security and Encryption Guide for more information on the CRL configuration options.

13. If you plan to create or already have multiple instances with deduplication storage, you must adjust the deduplication cache sizes so that the total memory of all instances does not exceed 75% of the physical RAM on the appliance.

    The default cache sizes are as follows:

    • MaxCacheSize: 50%

    • MaxPredictiveCacheSize: 20%

    • MaxSamplingCacheSize: 5%

    To tune the cache sizes on this instance:

    • Run the following command to tune the MaxCacheSize:

      sudo /usr/openv/pdde/pdag/bin/pdcfg --write /mnt/msdp/vol0/etc/puredisk/contentrouter.cfg --section CACHE --option MaxCacheSize --value <percent>%

      Where <percent> is the percentage of the appliance RAM to use for the cache on the instance.

    • Run the following command to tune the MaxPredictiveCacheSize:

      sudo /usr/openv/pdde/pdag/bin/pdcfg --write /mnt/msdp/vol0/etc/puredisk/contentrouter.cfg --section Cache --option MaxCacheSize --value <percent>%

      Where <percent> is the percentage of the appliance RAM to use for the predictive cache.

    • Run the following command to tune the MaxSamplingCacheSize:

      sudo /usr/openv/pdde/pdag/bin/pdcfg --write /mnt/msdp/vol0/etc/puredisk/contentrouter.cfg --section Cache --option MaxSamplingCacheSize --value <percent>%

      Where <percent> is the percentage of the appliance RAM to use for the sampling cache.

    • Restart the pdde-storage process with the following commands:

      sudo /etc/init.d/pdde-storage force-stop

      sudo /etc/init.d/pdde-storage start

14. If you selected MSDP storage for the instance, log in to the instance. Run the following command to create a backup policy to protect the MSDP catalog:

    sudo /usr/openv/pdde/pdcr/bin/drcontrol --new_policy --residence <storage unit> [--policy <policy name>] [--client<instance hostname>]

    Where <storage unit> is the name of the storage unit on which to store the MSDP catalog backups, and [--policy <policy name>] and [--client <instance hostname>] are optional.

    See the NetBackup Deduplication Guide for the other options that are available with the drcontrol utility.

15. (5250 appliances only) If you selected MSDP storage for the instance, use the following procedure to tune the MSDP parameters. Tuning the parameters increases backup and restore performance on the 5250 hardware.

    To tune the parameters on a 5250 appliance:

    • Log in to the instance as the appadmin user and run the following commands:

      • sudo /usr/openv/pdde/pdag/bin/pdcfg --write /mnt/msdp/vol0/etc/puredisk/contentrouter.cfg --section CRDataStore --option MaxFileSize --value 256Mib

      • sudo /usr/openv/pdde/pdag/bin/pdcfg --write /mnt/msdp/vol0/etc/puredisk/contentrouter.cfg --section CRDataStore --option WriteBufferSize --value 65536

    • From the home or tmp directory, restart the pdde-storage and mtstrmd processes with the following commands:

      • sudo /etc/init.d/pdde-storage force-stop

      • sudo /etc/init.d/pdde-storage start
