Display exports access cache configuration for all Vservers

Availability: This command is available to cluster administrators at the advanced privilege level.

Description

The vserver export-policy access-cache config show-all-vservers command displays the timeout attributes related to the exports access cache. The access cache maintains export rules applicable to a client that is accessing the volume or qtree. Data ONTAP obtains the access cache timeout values from the node where you run the command. The command output displays the following timeout parameters and their values:

  • TTL for Positive Entries: This is the TTL for positive entries in the access cache. During client access, if the TTL for the access cache entry that is allowing access has expired, that access cache entry will be refreshed. While the refresh is in progress, client access will be evaluated with the existing information in the access cache entry.

  • TTL for Negative Entries: This is the TTL for negative entries in the access cache. During client access, if the TTL for the access cache entry that is denying access has expired, that access cache entry will be refreshed. While the refresh is in progress, client access will be evaluated with the existing information in the access cache entry.

  • Harvest Timeout: If Data ONTAP does not use an entry that is stored in the access cache for this period of time, it deletes the entry.

Note This command is not supported in a cluster with effective cluster version of Data ONTAP 9.0.0 or later. The access cache settings are stored on a per-Vserver basis starting Data ONTAP 9.0.0. See the vserver export-policy access-cache config show command.

Examples

The following command displays the exports access cache timeout values for all Vservers in a cluster where the effective cluster version is earlier than Data ONTAP 9.0.0:

cluster1::*> vserver export-policy access-cache config show-all-vservers
     TTL For Positive Entries (secs): 36000
     TTL For Negative Entries (secs): 3600
              Harvest Timeout (secs): 43200
