120 TrueCopy for the XP128/XP1024/XP10000/XP12000
pair(s). You can split a TC390 pair only after the initial copy operation is complete. For more information
on split TC390 pairs, see ” Suspended Pairs ” on page 39.
Figure 65 Suspend Pair window (Asynchronous)
NOTE: When you set the several pairs at once and you want to keep some of the individual settings,
leave the parameter box blank. Then, only the parameters you enter are available.
Use the Suspend Pair window to select the Suspend Pair options for the pair(s):
• Volume: Device ID of M-VOL.
NOTE: If # is added to the end of an LDEV number, such as 00:3F#, the LDEV is an external
volume. For more information about external volumes, see Hitachi HPAV for z/OS User Guide.
• SSB [F/M = FB]: When this option is enabled (and PPRC Support = Yes), the MCU will notify all
attached hosts (IEA494I message) that the pair was suspended. This option should always be enabled.
NOTE: If PPRC support = No, the x’FB’ sense information will not be reported to the host, even if
the SSB (F/M = FB) suspend option is enabled.
• Suspend Kind: This option specifies the suspend type of the selected pair(s). The default setting is
R-VOL.
• M-VOL Failure. This setting can be used only for TC390 Synchronous pairs. The MCU will reject all
write I/O operations to the M-VOL while the pair is suspended, regardless of the fence level setting.
Use this setting if you need to maintain synchronization of the TC390 pair. This setting is functionally
equivalent to CSUSPEND with the optional PRIMARY parameter (without QUIESCE).
