Omconfig Discard Preserved Cache

Table 1. Omconfig Discard Preserved Cache . The following table describes the process to discard the preserved cache on the controller.

Description

Discards the preserved cache on the controller.

  • NOTE: To check if the controller has a preserved cache, type omreport storage controller controller=id . If the system displays Preserved Cache=yes, it indicates the presence of the preserved cache.

Syntax

omconfig storage controller action= discardpreservedcache controller=id force=enabled | disabled

If you set force=enabled, the cache is discarded irrespective of whether the controller detects a foreign or an offline virtual disk.

Example to

Discard the preserved cache.

Example

omconfig storage controller action= discardpreservedcache controller=1 force=enabled

  • CAUTION: Discarding the preserved cache can result in data loss. It is recommended that you run this command using the force=disabled option.
  • NOTE: If a foreign configuration is detected, then the preceding command using force=disabled option fails. To avoid data loss, import the foreign configuration and flush the preserved cache to disk. To discard preserved cache forcefully, either clear the foreign configuration and run the proceeding command, or run the proceeding command using force=enabled option.
