SIMs for HDP/HDT

The following table lists and describes the SIM reference codes associated with Dynamic Provisioning and Dynamic Tiering operations and provides solutions for the conditions.

SIM code (SIM level)	Event	Thresholds or values	Types of reports		Solutions
SIM code (SIM level)	Event	Thresholds or values	Sent to host?	Sent to maintenance personnel?	Solutions
620xxx* (Moderate)	Dynamic Provisioning pool usage level (Used (1%)) exceeded the Warning Threshold	1% to 100% (in 1% increments) Default: 70%	Yes	No	Solutions Add some pool-VOLs to the pool. Reclaim zero pages to release pages in which zero data are stored.
622xxx (Moderate)	Dynamic Provisioning pool is full	100%	Yes	No	Solutions Add some pool-VOLs to the pool. Reclaim zero pages to release pages in which zero data are stored. Remove all unnecessary Thin Image pairs that are associated with the primary volume. The Protect attribute of Data Retention Utility might have been set to the DP-VOLs. After performing above solutions, release the Protect attribute of the DP-VOLs.
623xxx (Moderate)	Error occurred in the Dynamic Provisioning pool	Not applicable	Yes	Yes	Contact Hitachi Solution Support Center.
624000 (Moderate)	No space in the shared memory	Not applicable	Yes	Yes	Solutions Remove pools that are not used. Remove DP-VOLs that are not used. Remove all unnecessary Thin Image pairs that are associated with the primary volume. Shrink the pool capacities.
625000 (Moderate)	Dynamic Provisioning pool usage level (Used (1%)) continues to exceed the highest pool threshold. SOM 734 must be enabled.	Highest pool threshold of Dynamic Provisioning	Yes	No	Solutions Add some pool-VOLs to the pool. Reclaim zero pages to release pages in which zero data are stored. Remove all unnecessary Thin Image pairs that are associated with the primary volume.
626xxx (Moderate)	Dynamic Provisioning Pool usage level (Used (1%)) exceeded the Depletion Threshold	1% to 100% (in 1% increments) Default: 80%	Yes	No	Solutions Add some pool-VOLs to the pool. Reclaim zero pages to release pages in which zero data are stored. Remove all unnecessary Thin Image pairs that are associated with the primary volume.
627xxx (Moderate)	Pool-VOL is blocked	Not applicable	Yes	Yes	Contact Hitachi Solution Support Center.
628000 (Service)	Protect attribute of Data Retention Utility is set	Not applicable	Yes	Yes	Solutions Add pool-VOLs to the pool to increase the free space in the pool. Reclaim zero pages to release pages in which zero data are stored. Contact Hitachi Solution Support Center to restore the pool-VOL. If the blocked pool-VOL is an external volume, verify the status of the path blockade and the external storage system. After performing the above solutions, release the Protect attribute (Data Retention Utility) of the DP-VOL.
629xxx (Moderate)	In the Dynamic Provisioning pool, the used capacity reserved for writing exceeded the Warning Threshold. This SIM is reported if the Dynamic Provisioning pool contains one or more LDEVs in the parity group with accelerated compression enabled.	1% to 100% (in 1% increments) Default: 70%	Yes	No	Estimate the FMC capacity to be added, and then add the FMC capacity.
62Axxx (Moderate)	In the Dynamic Provisioning pool, the capacity reserved for writing is full. This SIM is reported if the Dynamic Provisioning pool contains one or more LDEVs in the parity group with accelerated compression enabled.	100%	Yes	No	Estimate the FMC capacity to be added, and then add the FMC capacity.
62B000 (Moderate)	In theDynamic Provisioning pool, the used capacity reserved for writing continues to exceed the highest pool threshold. SOM 734 must be enabled. This SIM is reported if the Dynamic Provisioning pool contains one or more LDEVs in the parity group with accelerated compression enabled.	Highest pool threshold of Dynamic Provisioning	Yes	No	Estimate the FMC capacity to be added, and then add the FMC capacity.
62Cxxx (Moderate)	In the Dynamic Provisioning pool, the used capacity reserved for writing exceeded the Depletion Threshold. This SIM is reported if the Dynamic Provisioning pool contains one or more LDEVs in the parity group with accelerated compression enabled.	1% to 100% (in 1% increments) Default: 80%	Yes	No	Estimate the FMC capacity to be added, and then add the FMC capacity.
62Dxxx (Moderate)	In the Dynamic Provisioning pool, the used capacity reserved for writing exceeded the Prefixed Depletion Threshold. This SIM is reported if the Dynamic Provisioning pool contains one or more LDEVs in the parity group with accelerated compression enabled.	90%	Yes	No	Estimate the FMC capacity to be added, and then add the FMC capacity.
62Exxx	Dynamic Provisioning pool usage level exceeded the depletion threshold. This SIM is output when the pool option "Suspend TI pairs when depletion threshold is exceeded" is enabled.	Depletion threshold	Yes	No	Solution: Resolve the cause of SIM 626xxx (depletion threshold exceeded), and then delete snapshot data and create the pair again for the Thin Image pair whose pair status is PSUE.
641xxx (Service)	In the Dynamic Tiering pool, the tier relocation operation is suspended by the system. This SIM can be displayed if "Notify an alert when tier relocation is suspended by system" is enabled on the "Edit Advanced System Settings" window.	Not applicable	Yes	Yes	Determine why the tier relocation was suspended.
