If a Version 2 Relationship is Suspended
Version 2 relationships m ay be suspended if a hardware or software failure occurs during a Version
2
operation. If Version 2 relationships are suspended, hosts may be unable to access the copy target
datasets.
To find whether suspended Version 2 relationships exist within the volumes, use the Pair Op eration
window (see “Pair Operation Window” on page 67). If the Relationship(S) column of the volume list
displays S-Failed or T-Failed, a suspended Version 2 relationship exists within the volume.
To delete a suspended Version 2 relationship, do one of the following:
• Delete the copy target dataset that has the suspended Version 2 relationship (that is, the dataset
that is
inaccessible from the hosts). The operating system will automatically recognize the p air
that has
the dataset to be d eleted, and will issue the Withdraw command.
• Issue the TSO FCWITHDR command. If the suspended Version 2 relationship can be identified,
issue the FCWITHDR c om m a nd to its extent. For detailed i nformation about the FCWITHDR
command, see “Releasing a Version 2 Relationship Using FCWITHDR” on page 83.
SIM Reporting
The subsystem reports a service information m essage (SIM) to the host when it is necessary to notify the
user of a possible service requirement for the subsystem. The SIMs are classified according to severity
for reporting and logging purposes:
1. Service
2. Moderate
3. Serious
4. Acute
The larg
er the
number, the more important the message. The SVP reports all SIMs related to Version 1
and
Vers
ion 2 op erations, and all SIMs are store d on the SVP for use by the HP service representative.
The SIMs reported to the z Series a nd S/390 host are logged in the SYS1.LOGREC dataset of the host
operating system. Each time a SIM is generated, the amber Message LED on the control panel (under the
Ready and Alarm LEDs) turns on as an additional alert for the user. The Remote Web Console computer
also di
splays the SIMs to provide an additional source of notification for the user.
Note: For further information on SIM reporting, contact your HP service representative or HP technical
support.
The fol
lowing figure shows a typical 32-byte SIM from the subsystem.
