Setting the access option

The snapvault.access option controls which storage systems can request data transfers. This option persists across reboots.

Steps

1. On the primary storage system: To set the primary storage systems to grant access only to the secondary storage system, enter the following command: options snapvault.access host= snapvault_secondary

   Setting this option on the SnapVault primary storage system determines which secondary storage system can access data from that primary storage system.

2. On the secondary storage system: To allow the primary storage systems to restore data from the secondary storage system, enter the following command: options snapvault.access host= snapvault_primary1, snapvault_primary2 ...

   Setting this option on the SnapVault secondary storage system determines which SnapVault primary storage systems can access the secondary storage system.

   The system must be able to resolve the host name entered as snapvault_primary to an IP address in the /etc/hosts file, or else the system needs to be running DNS or NIS. You can also use the literal IP address instead of the host name. The syntax for specifying which systems are allowed access to the secondary storage system is described in the na_protocolaccess(8) man page. For more information about the options command, see the na_options(1) man page.
