Turning TCz Links Around option.
Determines whether Quick or Steady, if not specified, is
performed at the execution of pairresync by CCI.
Mode 122 = ON: Steady is performed.
Mode 122 = OFF: Quick is performed. Preventing Mode 87 at
the pairresync execution by CCI without NormalCopy nor
QuickResync specified.
Suppression of high speed micro-program exchange for CHT.
TCz – Allows you to update the VOLSER and VTOC of the
R-VOL while the pair is suspended if both mode 20 and 190
are ON.
High-Speed Format for Virtual LVI/LUN (VLL) (available for all
device emulation types).
(1) High-Speed Format support: When redefining all LDEVs in
an array group using VLL Volume Initialize or Make Volume
operation, LDEV format, as the last process, will be performed
in high speed.
(2) Make Volume feature enhancement: The Make Volume
operation (recreating new CVs after deleting all volumes in a
VDEV) is now supported for all device emulation types.
Mode 269 = ON: The High Speed format is available when
performing VLL operations on Storage Navigator (or LDEV
format (SVP Maintenance) for all LDEVs in a array group).
Mode 269 = OFF: Only the low-speed format is available when
performing VLL operations on Storage Navigator (and LDEV
format operations on SVP Maintenance).
Note: If mode 503 is ON, since the format processing is
prevented, the High Speed Format function for VLL operations
(mode 269 ON) is not available. For details on the relationship
between modes 503 and 269, see
below.
Note: Mode 269 is effective only when using the SVP to
format the CVS.
Tru64 (Host Mode 07) and OpenVMS (Host Mode 05)
Caution: Host offline: Required
Issuing OLS when Switching Port
When the mainframe host (FICON) is connected with the CNT-
made FC switch (e.g., FC9000) and is using along with the
TrueCopy for z/OS with Open Fibre connection, the occurrence
of Link Incident Report for the mainframe host from the FC
switch will be deterred when switching the CHT port attribute
(including automatic switching when executing CESTPATH and
CDELPATH in case of mode 114 = ON).
Mode 292 = ON: When switching the port attribute, issue the
OLS (100 ms) first, and then reset the Chip.
Mode 292 = OFF: When switching the port attribute, reset the
Chip without issuing the OLS.
Pre-labeling: Pre-label is added via SVP as tentative volume
serial name into logical device formatting.
