Hitachi TrueCopy for z/OS (T1711-96009, June 2006)

156 TrueCopy for the XP1024/XP128/XP12000/XP10000
CAUTION: The QUIESCE option of the CSUSPEND command has been disabled by APAR OW15247 or
APAR OW15248. For detailed information on the QUIESCE option of the CSUSPEND command, refer to
either of these APARs. Check with your HP account team before using the CSUSPEND command with the
QUIESCE option to suspend TC390 volume pairs on an XP1024/XP128/XP12000/XP10000 (or other XP
disk array). If the CSUSPEND command with the QUIESCE option is issued to certain volumes (for
example, active SPOOL, PAGE, or CATALOG datasets, or active SYSRES volume), the attached host(s) may
enter a deadlock condition and may require a storage control IML to correct the condition. TC390A does
not support the CSUSPEND/QUIESCE option.
Using PPRC TSO Commands with TrueCopy Asynchronous
For TC390A operations, special switches and parameters are used to control and monitor TC390A pairs
and groups using PPRC commands. This section describes this special use of PPRC TSO commands for
TC390A volumes on the XP1024/XP128/XP12000/XP10000. Table 34 on page 156 describes the
typographic conventions used for the PPRC TSO commands described in this section.
NOTE: PPRC TSO command parameter support depends on the emulation (for example, 2105 or 3990).
PPRC command extensions are supported when running with 2105 emulation.
Use the PPRC TSO Command option on the Async Option window to select the XP256-compatible format
for PPRC TSO commands (groups 0-F instead of 00-3F).
NOTE: The DEVSERV PATHS command displays the pair status of a TC390A volume in the DC-STATE box.
The contents of this box are the same as for TC390 Synchronous. Note that the TC390A transition states
(suspending and deleting) are not displayed.
This section does not specifically address the equivalent PPRCOPY ICKDSF commands. Use caution when
issuing ICKDSF commands to TC390A volumes.
CESTPATH
Use the CESTPATH command to establish remote copy paths for the XP1024/XP128/XP12000/XP10000
and can be used for either serial or Fibre Channel interface. However, the ESCON® cable connection is
not supported for the XP1024/XP128/XP12000/XP10000.
For fibre, the RCU controller ID is specified. The syntax for the CESTPATH command (ESCON Interface) is:
For 3990-3, -6 and -6E controller emulations:
CESTPATH DEVN(X’dev#’) PRIM(X’ssid’ serial#) SEC(X’ssid’ serial#’) LINK(X’aabbccdd’)
