Function
This command is a TSO/E command called from REXX scripts.
This command acquires the operating information for the specified copy group.
If the copy type is CAJ, the command acquires journal group operating information from both the
master journal and restore journal storage systems.
Parameters
STEM(stem-name- 1 ) ~ <REXX prefix of 64 or fewer characters>
Specify the prefix of the name of the copy group structure that stores information about the copy
group for which you want to acquire operating information. Specify the same character string as
the one specified in the STEM parameter of the YKLOAD command that loaded the corresponding
copy group. You must also include a trailing period character.
The operating information is set under STATS.n in the copy group structure.
MSG(stem-name-2) ~ <REXX prefix of 64 or fewer characters>
Specify an optional prefix for the name of the message structure used to store the messages to be
generated by this command. You must also include a trailing period character.
The message structure is initialized when the CLI command with the same name as the MSG
parameter is specified.
NOTE:
Start Usage Monitor from the Remote Web Console before executing the YKSTATS command.
Set the collection interval of Usage Monitor information to 10 minutes or less.
If the specified copy group is a CAJ copy group and contains the following volumes, in order
to obtain correct information, you must start Usage Monitor for the CU containing the journal
volumes used by the copy group.
◦
HP XP24000/XP20000 Disk Array volumes
◦
HP P9500 Disk Array
If the specified copy group is a CAA copy group and contains only HP XP24000/XP20000
Disk Array volumes, you do not need to start Usage Monitor.
When CAA is used, the storage system serial number that is set in the REXX variable is the
information obtained from the storage system. When CAJ is used, the storage system serial
number that is set in the REXX variable is the value specified in the configuration file.
Before using the YKSTATS command to obtain operating information, use the
YKQUERY/YKEWAIT command to check if the copy pair status has been set. If no command
is entered, a determination is made based on the copy group status for the YKQUERY/YKEWAIT
command, and N/A might be displayed for operating information.
