The storage system sends a service information message (SIM) to the host to notify the user of a possible service requirement for the storage system.

SIMs are classified according to severity for reporting and logging purposes.

Service
Moderate
Serious
Acute

The message number indicates the importance: the larger the number, the more important the message. The storage system reports SIMs when maintenance of the storage system is required. The storage system reports all SIMs for Compatible FlashCopy^® operations. All SIMs are reported to the mainframe host and logged in SYS1.LOGREC of the host's OS. All SIMs are also recorded in the storage system, and then reported to the operation terminal of the management tool.

The following figure shows a typical 32-byte storage system SIM.

Figure. Typical SIM showing the reference code and SIM type

SIMs are displayed on the host console by reference code (RC) and severity. The six-digit RC (bytes 13, 22, and 23) identifies the error and determines the severity. The SIM type (byte 28) indicates the component that experienced the error.

The following table shows the SIM specific to SIz operations.

Table. SIz SIM
Reference code			SIM type (byte 28)	Importance level	Description
SSB22	SSB23	SSB13	SIM type (byte 28)	Importance level	Description
4b	2`x`	`yy`	FE	Moderate	Copying process of Compatible FlashCopy^® terminates abnormally. Internally the relationship becomes suspended by the failure, and the T-VOL becomes partially inaccessible. `x` indicates the last digit of the T-VOL's CU number (00 to FE). `yy` indicates the LDEV number of the T-VOL. In the case of a tier memory access error, SIM=4b4`xyy` is output rather than this SIM. Tier memory is an area for storing relationship information. For SIM=4b4`xyy`, see the following item in this table.
4b	4`x`	`yy`	FE	Moderate	Copying process of Compatible FlashCopy^® ends abnormally because of a tier memory access error. Internally the relationship becomes suspended by failure, and the T-VOL becomes partially inaccessible. `x` indicates the last digit of the CU number of the failed volume (00 to FE). `yy` indicates the LDEV number of the failed volume.
47	e5	00	F1	Moderate	The Compatible FlashCopy^® relationship is automatically withdrawn, and the T-VOL becomes inaccessible because the power supply was turned on while the shared memory volatilized.
7f	f1	05	F1	Service	If either SIM=4b2`xyy` or SIM=4b4`xyy` is output, further output of either type of SIM is inhibited for five minutes. For example, if SIM=4b4111 is output, SIM=4b4`xyy` is not output for five minutes, regardless of `xyy`. This SIM reports the occurrence of this delay.
