Change DHSM connection settings

Modify settings for an existing DHSM connection.

Format

/net/nas/dhsmconn –id <value> modify [-async] [-mode {enabled | disabled | recallOnly}] [-readPolicy {full | passthrough | partial | none}] [-secondaryServerName <value> [-secondaryPort <value>] [-localPort <value>] [-secondaryUsername <value> -secondaryPassword <value>] [-timeout <value>]

Action qualifiers

QualifierDescription
-idDHSM connection identifier.
-mode Sets the mode of Unity DHSM operations on the specified file system. Valid values are:
  • enabled (default) – allows both the creation of stub files and data migration through reads and writes
  • disabled – neither stub files nor data migration is possible. Data currently on the Unity can be read and written to in the disabled mode.
  • recallOnly – the policy engine is not allowed to create stub files, but the user is still able to trigger data migration using a read or write request from the secondary file system to the Unity.
-readPolicy Specifies the migration method option used by the Unity in the connection level, to override the migration method specified in the stub file. Valid values are:
  • none (default) – specifies no override.
  • full – recalls the whole file to Unity on a read request before the data is returned.
  • passthrough – retrieves data without recalling the data to Unity.
  • partial – recalls only the blocks required to satisfy the client read request.
-secondaryServerName Specifies the remote server name or IP address.
-secondaryPort Specifies the remote port number that the NAS server delivers the HTTP request to. If not specified, the NAS server issues HTTP requests to port 80 on the secondary storage HTTP server.
-secondaryUsername Defines the username the HTTP client uses if digest authentication is required by the secondary storage HTTP server.
-secondaryPassword Specifies the password associated with the username required by the secondary storage server.
NOTE:The password must be 8 to 64 characters in length, contain at least one upper and lower case letter, and one numeric. The password cannot include the single quote ('), ampersand (&), or space characters.
-timeout Specifies the timeout value in seconds. By default, the Unity HTTP client waits 30 seconds for a reply from the HTTP server and then retries the operation once.

HTTP connection
