97 HXRC – Variable Sleep Wait timer duration (see modes 45, 85, 86; see ” HXRC device blocking and
load balancing ” on page 216).
Mode 97 OFF: Sleep Wait timer duration = 100 ms.
Mode 97 ON: Sleep Wait timer duration = 10 ms.
98 HXRC – Selects SCP or session cancel (see modes 45, 85, 86; see ” HXRC device blocking and load
balancing ” on page 216).
Mode 98 OFF: SCP.
Mode 98 ON: Forced session cancel.
104 TC390 CGROUP – Selects disk array default for CGROUP FREEZE option. Applies to 3990 emulation
only.
Mode 104 is invalid if the controller emulation is 2105
or 2107 . For 2105 or 2107 use the CGROUP
option of CESTPATH.
Mode 104 ON: FREEZE enabled.
Mode 104 OFF (default): FREEZE disabled.
114 TC390 – Allows dynamic port mode setting (RCP/LCP for serial, Initiator/RCU target for Fibre Channel)
through PPRC CESTPATH and CDELPATH commands.
Mode 114 ON: Initiator ports will automatically change to RCU target ports. or vice versa.
Mode 114 OFF (default): Initiator ports will not automatically change to RCU target ports, nor vice
versa.
For Fibre Channel interface, do not use the CESTPATH and CDELPATH commands at the same time as
the SCSI path definition function of LUN Management. The Fibre Channel interface ports need to be
configured as initiator ports or RCU target ports before the CESTPATH and CDELPATH commands are
issued.
NOTE: Even if you set ON for SVP system option mode mode 114, initiator ports will not
automatically change to RCU target ports, nor vice versa, when these ports are in
initiator/external mix mode.
Before issuing the CESTPATH command, verify that the relevant paths are offline from the host(s) (for
example, configure the Chipid offline, deactivate the LPAR, or block the port in the ESCD). If any active
logical paths still exist, the add path operation will fail because the port mode (LCP/RCP) cannot be
changed.
