Editing the options file dsm.opt

Edit online

Most of the options in the dsm.opt file affect the backup-archive client. However, some options affect the space management client.

About this task

Table 1 provides a brief description of the space management options that you can set in your dsm.opt file.

Note: The IBM Storage® Protect nfstimeout option is ignored for the space management client. The space management client operates only on local file systems.

Procedure

  1. Group the options into stanzas for each server that your client node contacts for backup, archive, and space management services.
  2. Enter a value for each option and remove the leading asterisk (*).
    Table 1. space management client options in the dsm.opt file
    Option Default Description
    defaultserver The server that you identify in the first stanza of the dsm.sys file. Specifies the name of the default IBM Storage Protect server to contact for space management services when you do not specify a server name on the migrateserver option. The value of defaultserver in the dsm.sys file overrides defaultserver in the dsm.opt file. See defaultserver.
    hsmgroupedmigrate NO When this option is set to YES, the HSM transaction grouping is activated. Multiple files are migrated in each transaction with the IBM Storage Protect server. The files are migrated when either the transaction byte limit or the transaction group limit is reached. The transaction group limit is specified with the txngroupmax option, which is set on the IBM Storage Protect server. See hsmgroupedmigrate.
    migrateserver The value of defaultserver option. Specifies the IBM Storage Protect server to which you want to migrate files from your client node. Specify only 1 server for each client node. The value of migrateserver in the dsm.sys file overrides migrateserver in the dsm.opt file. See migrateserver.
    restoremigstate YES Restores a file to stubbed (migrated) state. The file must have been backed up after migration or premigration. IBM Storage Protect records the migration state of files during backup, so only files that were migrated or premigrated before backup can be restored to stubbed (migrated) state. See restoremigstate.
  3. Set the DSM_CONFIG environment variable to point to your dsm.opt file.
