Workflow for fixing errors when SIMs related to cache management devices are reported

The Reference code 670000 SIM (service information message) is issued if the number of the remaining cache management devices falls below 4,096.

For more information about SIM reference codes, contact customer support.

You can view SIMs that occur in the storage system in an HDvM - SN window.

For more information about checking alerts and the details of a SIM, see the System Administrator Guide for your storage system.

You must reserve enough cache management devices. If a warning SIM is issued before you deplete cache management devices, a problem has not necessarily occurred.

Use the following workflow to fix errors when the warning SIMs related to cache management devices are reported. You must have the Storage Administrator (Provisioning) role to use this workflow.

1. Confirm that the number of remaining cache management devices meets the threshold for your storage system (at least 4,096).
2. Remove unneeded V-VOLs.
3. Remove all of the unneeded Thin Image Advanced snapshots for the P-VOLs by resynchronizing the pairs.
4. (VSP 5000 series) Manually complete the SIMs related to cache management devices.
