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.
