Sysplex DASD Device attributes

The Sysplex DASD Device attribute group monitors z/OS image-by-image activity for individual DASD devices.

Address Device address for the system in hexadecimal format.

Average Response Time Average I/O response time, in milliseconds, of the device as seen by the system. Valid value is a numeric value in the range 0 through 2147483647, to one decimal point precision, and includes the use of the *AVG, *MAX, *MIN, or *SUM functions. An example is 55.2.

Bypass Filtering This attribute is for information only. You can use this attribute in a situation.

Cache Status Cache status of the device for the system. Valid values include:

Connect Time Average connect time in milliseconds, for a typical I/O. Valid value is a numeric value in the range 0 through 2147483647, to one decimal point precision, and includes the use of the *AVG, *MAX, *MIN, or *SUM functions. An example is 21.2.

Disconnect Time Average disconnect time, in milliseconds, for a typical I/O. Valid value is a numeric value in the range 0 through 2147483647, to one decimal point precision, and includes the use of the *AVG, *MAX, *MIN, or *SUM functions. An example is 12.8.

I/O Rate Average I/O rate for the device. Valid value is a numeric value in the range 0 through 2147483647, to one decimal point precision, and includes the use of the *AVG, *MAX, *MIN, or *SUM functions. An example is 12.8.

Indexed VTOC Status of the indexed volume table of contents (VTOC) as seen from the system. Valid values are:

IOSQ Average IOS queue time, in milliseconds, for a typical I/O. Valid value is a numeric value in the range 0 through 2147483647, to one decimal point precision, and includes the use of the *AVG, *MAX, *MIN, or *SUM functions. An example is 15.5.
