SHARED PUBSET report

The SHARED PUBSET report contains monitored data on I/O operations to disk devices of shared pubsets for a computer network.

Report output

The REPORT SHARED_PUBSET statement is used to request the output of the SHARED PUBSET report.

The monitored data under SERVICETIME is only output when the SM2 administrator

• uses the SET-SAMPLING-DEVICE-PARAMETERS statement to define the monitoring of the service times and

• uses the statement START-MEASUREMENT-PROGRAM TYPE=*SAMPLING-DEVICE to start monitoring.

When the SM2 subsystem is started, the SAMPLING-DEVICE monitoring program is started without the service times being recorded.

The privileged user can use the SELECT-HOSTS statement to select the hosts whose monitored data is to be displayed in the report.
The header contains information on the local host (if this is selected) or on first host for which valid data is found. If valid information cannot be found on a particular host, the string SOME DATA MISSED appears in the second line.
Only the monitored data of the local host is displayed to the nonprivileged user.

Overflow screens may be requested for this report.
The output is sorted on the basis of the sum of READ (IO/S) and WRITE (IO/S).

SM2 is not notified of device management commands (see the “Commands” manual [3]). In the monitoring cycle in which such commands are entered, incorrect data may be produced for the affected devices.

For parallel access volumes (PAV), the following applies:

Only base devices are output. The monitored data refers to the base device and the assigned alias devices.

For information on PAV see the “Introduction to System Administration” manual [6].

Monitoring information

The values correspond to those of the DEVICE DISK report and form the sum of the values from the individual hosts.

MN	Mnemonic name of the disk device
VOLUME	VSN of the disk device or spaces (e.g. if the disk belongs to a pubset that has not been imported)
Q LGTH	Average length of the device queue including the jobs that are currently being dealt with
RSC	Average number of parallel processed RSC IOs (x86 servers)
READ	Number of input operations or number of kB transferred per second
WRITE	Number of output operations or number of kB transferred per second
SERVICETIME
HW (MS)	Average hardware service time in milliseconds
SW (MS)	Average software service time (including hardware service time) in milliseconds
