CACHBAT

The cache battery pack might be failing.

  1. Use the cache battery pack location information in the service action log (SAL) if it is available. If the location is not available, use the address of the storage IOA. See the System reference code format description to find the location code for the storage IOA.

    Using the location code, see Part locations and location codes to identify the storage IOA.

  2. Use Table 1 below to determine the service action. If more than one location code is listed in the table for the cache battery pack, and the location of the cache battery pack is not available in the SAL, continue with step 3 to identify the location.
    Note: The 571F/575B combination storage and auxiliary cache IOA card set uses two card slot locations. The battery pack is located on the 575B side of the card set, regardless of the location found in the previous steps. The 572F/575C combination storage and auxiliary cache IOA card set also uses two card slot locations. The battery pack is located on the 575C side of the card set, regardless of the location found in the previous steps.

  3. Perform the following actions to determine the location of the cache battery pack:
    1. Record the resource name from the product activity log (PAL) or SAL entry for this error.
    2. From the Start a Service Tool display, select Hardware service manager > Locate resource by resource name.
    3. Enter the resource name of the storage IOA that you recorded from the PAL or SAL entry.
    4. Select Display detail.
    5. The PCI bus number is shown in decimal.
    6. Use Table 2 to determine the location of the cache battery pack. Then use Table 1 to determine the service action.
