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

Control Unit Type Type of control unit. Valid values are:

  • Unknown
  • 3880-23
  • 3990-1
  • 3990-2
  • 3990-3
  • 3990-6

Cumulative I/O Rate Sum of the I/O rate in seconds as seen from each sharing 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 45.1.

Device Contention Index Indication of I/O delay for this group caused by intersystem contention for the device. The larger the number, the more severe is the contention. Valid value is a numeric value in the range 0 through 2147483647, to two decimal point precision, and includes the use of the *AVG, *MAX, *MIN, or *SUM functions. An example is 1.35.

Device Type Device type. Valid values are 3380 and 3390.

Group Name Name of the DASD group. Valid format is a simple text string from 1 through 30 characters; for example, SGDB2X.

Managed System A sysplex in your enterprise that is being monitored by IBM® Z OMEGAMON AI for z/OS agents, in the format <plexname>:MVS:SYSPLEX. Valid value is a character string with a maximum length of 32 bytes.

True Percent Busy Device true busy value. Valid value is a numeric value in the range 0 through 100, to one decimal point precision, and includes the use of the *AVG, *MAX, *MIN, or *SUM functions. An example is 25.5.

Volume Serial Number Volume serial number of the device. Valid format is a simple text string from 1 through 6 characters; for example, VOL001.

Worst Disconnect Time Worst disconnect time, in milliseconds, as seen from one system. Valid value is a numeric value in the range 0 through 100, to one decimal point precision, and includes the use of the *AVG, *MAX, *MIN, or *SUM functions. An example is 2.5.

Worst Disconnect Time System System where the worst disconnect time was observed. Valid value is a simple text string from 1 through 32 characters; for example, SYSA.

Worst Response Time Worst response time, in milliseconds, as seen from one system. Valid value is a numeric value in the range 0-2147483647, to one decimal point precision, and includes the use of the *AVG, *MAX, *MIN, or *SUM functions. An example is 242.5.

Worst Response Time System System where the worst response time was observed. Valid value is a simple text string from 1 through 32 characters; for example, SYSA.
