4.2 Upgrading the Media Format for Existing NSS Volumes

4.2.1 Upgrading the Media Format

The media format upgrade process runs in the background. The elapsed time for the upgrade process varies according to the number of storage objects in the volume; the more objects a volume contains, the longer it takes. Volumes with a large number of objects can take a substantial time to upgrade.

The commands in this section perform the one-time upgrade for currently active NSS volumes. A message is sent to the logger screen when the process is successfully completed.

Issue the commands at the server console on NetWare as the administrator user, or in the NSS Console (nsscon) in a Linux terminal console as the root user.

nss /ZLSSUpgradeCurrentVolumeMediaFormat=volumename

Upgrades the specified active volume. If it is a shared volume, the clustering system vetoes the upgrade until all nodes in the cluster are running a supported operating system.

nss /ZLSSUpgradeCurrentVolumeMediaFormat=all

Upgrades all currently active volumes. If a shared volume is encountered, the clustering system vetoes the upgrade until all nodes in the cluster are running a supported operating system.

nss /ZLSSUpgradeCurrentVolumeMediaFormat=all /include=shared

Upgrades all currently active volumes that are part of a shared pool, but only if the clustering system permits it.

nss /ZLSSUpgradeCurrentVolumeMediaFormat=all /include=local

Upgrades all currently active volumes that are not part of a shared pool.

nss /ZLSSUpgradeCurrentVolumeMediaFormat=all /include=local,shared

Upgrades all currently active volumes whether they are shared or local. If a shared volume is encountered, the clustering system vetoes the upgrade until all nodes in the cluster are running a supported operating system.

4.2.2 Enabling Hard Links After the Media Upgrade

After the media is upgraded successfully, you must set the Hard Links attribute on volumes where you want to create hard links. The Hard Links attribute is automatically enabled if there are existing hard links on the volume. For information about using hard links on NSS volumes, see Section 24.0, Managing Hard Links.

IMPORTANT:Do not attempt to enable the Hard Links attribute until the upgrade process is complete.

  1. Issue the following commands at the server console on NetWare as the administrator user, or in the NSS Console (nsscon) in a Linux terminal console as the root user.

    Command

    Description

    		 
    nss /HardLinks=volumename

    Enables the Hard Links attribute for a specified volume. This enables hard links to be created on the volume.

    		 
    nss /HardLinks=all

    Enables the Hard Links attribute for all NSS volumes on the server. This enables hard links to be created on any volume on the server. Any given hard link can point only to a file on the same volume.

  2. You can verify that the hard links attribute is set for the volume by entering the following command at the server console on NetWare, or at the NSS Console (nsscon) on Linux:

    volumes

    The Hard Links attribute appears in the Attributes column for volumes where it is enabled.
