12.2 Browsing NSS Volumes and Performing Actions on Them

The NCP Server plug-in to OES Remote Manager appears as “Manage NCP Services” in the left panel. NCP volumes and NSS volumes are listed as NCP Shares.

For detailed information about creating and managing NCP volumes, see the OES 2018 SP2: NCP Server for Linux Administration Guide.

For detailed information about creating and managing NSS volumes, see the OES 2018 SP2: NSS File System Administration Guide for Linux.

For detailed information about creating and managing Dynamic Storage Technology shadow volume pairs with NSS volumes, see the OES 2018 SP2: Dynamic Storage Technology Administration Guide.

12.2.1 Viewing Information about an NSS Volume

  1. In OES Remote Manager, select Manage NCP Services > Manage Shares.

  4. In the Information table, view the following information about the NSS volume:

    • File system path on Linux, such as /media/nss/VOLD

      Click the link to browse the directories and files on the volume.

      Click the link to browse the directories and files on the pair’s secondary volume.

    • Loaded name spaces, such as DOS, LONG, MAC, and UNIX

    • File system type (NSS)

    • NCP volume ID

      The NCP volume ID is a value between 0 and 254 that is automatically assigned for standalone volumes, beginning with zero. The SYS volume is by default assigned 0, and _Admin is assigned 1. For shared volumes, the volume ID is specified in the cluster load script for shared volumes, beginning with 254 and down.

    • Status

      Identifies whether the volume is mounted/unmounted, online/offline, or in a cluster resource. It lists the NSS volume attributes that are enabled for the volume, such as Salvageable, User Quotas, Directory Quotas, and so on.

12.2.5 Salvaging and Purging Deleted Files on an NSS Volume

From an NSS volume’s Share Information page, the Salvageable File List option allows you to view a list of deleted files that are available for salvage or purge on the volume. Deleted files are available only for NSS volumes where the Salvage attribute is enabled. For information about the NSS file salvage feature, see Volume Salvage versus File Salvage in the OES 2018 SP2: NSS File System Administration Guide for Linux.

  1. In OES Remote Manager, select Manage NCP Services > Manage Shares.

  2. In the right pane, view the list of mounted NSS volumes in the Active Shares list.

  3. Next to the volume name, click the Information icon (I) to go to the volume’s Share Information page.

  4. Below the Information table, click Salvageable File List to open the Salvage File Information page.

  5. Salvage or purge files in the list:

    If the deleted file resided in a directory that has been deleted, you must first salvage the deleted directories in the path. Salvage each lower directory in turn until you have salvaged the deleted directory that contained the file. You can then search for the deleted file in the salvaged directory.

    • The Purge all files option allows you to purge all deleted files on the selected volume.

    • The Salvage option allows you to recover a deleted file.

    • The Purge option allows you to purge a deleted file.

      You can also select a deleted directory and use this option to purge the deleted directory and all of the deleted subdirectories and files that it contains.

12.2.6 Purging a Deleted NSS Volume

For volume salvage, the NSS volumes are automatically retained on deletion. The deleted volume can be salvaged for a period of time that is determined by the server-level Logical Volume Purge Delay setting. Administrators with the Supervisor right can salvage or purge deleted volumes at any time before the purge delay elapses. For information about the NSS volume salvage feature, see Volume Salvage versus File Salvage in the OES 2018 SP2: NSS File System Administration Guide for Linux.

  1. In OES Remote Manager, select Manage NCP Services > Manage Shares.

  2. In the right pane, view the list of mounted NSS volumes in the Active Shares list.

  3. Next to the volume name, click the Information icon (I) to go to the volume’s Share Information page.

  4. Scroll down to the Volume Tasks table, then click Purge Volume.
