Device adapters

View the information that is shown about device adapters in DS8000® block storage systems.

The following information is shown for each device adapter:

Acknowledged: Shows whether a user marked the status of a device adapter as acknowledged. An acknowledged status indicates that the status was reviewed and is either resolved or can be ignored. An acknowledged status is not used when the status of related, higher-level resources is determined.; For example, if a device adapter has an error status, the related storage system also shows an error condition. If the error status of the device adapter is acknowledged, it changes to Error-Acknowledged. This acknowledged status is then treated as normal, and is used in evaluating the overall condition of the storage system. In this case, if the other internal resources of the storage system are also normal, the storage system condition is considered normal.
Name: The identifier for the device adapter that includes code and location.
For example, for IBM®.1400-1B3-75766/R0-P1-C6, the value IBM.1400-1B3-75766/R0 represents the code and P1-C6 represents the location.
Frame: The unique identifier of the equipment frame for the device adapter. The DS8000 hardware unit where the device adapter is located.
I/O Enclosure: The ID of the enclosure that is associated with the device adapter.
Status: The status of a device adapter. Values include Operational, Warning, and Error. If the adapter has an error status, identify and correct the problem immediately.
Device adapter pair: The pair ID that is associated with the device adapter. Device adapter pairs are located in I/O enclosure pairs.
An even-numbered device adapter pair ID indicates the first device adapter pair in an I/O enclosure pair. An odd-numbered device adapter pair ID indicates the second device adapter pair in an IO enclosure pair.
Location: Specifies the I/O enclosure and the device adapter location.
The I/O enclosure location format is Uttt.mmm.ppsssss.
Example: U1400.1B3.RJ49745-P1-C3.

The device adapter location format is Pn-Cn where Pn indicates the Planner number (1) and Cn indicates the card number (1 - 6).
Serial number: The unique identifier of the device adapter.
Example: YM10BK04W2JN.
