269 Common High Speed Format for CVS (Available for all dku
emulation type)
(1) High Speed Format support
When redefining all LDEVs included in an ECC group
using Volume Initialize or Make Volume on CVS
setting panel, LDEV format, as the last process, will
be performed in high speed.
(2) Make Volume feature enhancement
In addition, with supporting the feature, the Make
Volume feature (recreating new CVs after deleting
all volumes in a VDEV), which so far was supported
for OPEN-V only, is available for all emulation types.
Mode 269 = ON :
The High Speed format is available when
performing CVS operations on Storage Navigator or
performing LDEV formats on the Maintenance
window of the SVP for all LDEVs in a parity group.
Mode 269 = OFF (default):
As usual, only the low speed format is available
when performing CVS operations on Storage
Navigator. In addition, the LDEV specifying format
on the Maintenance window of the SVP is in low
speed as well.

292 HRC Issuing OLS when Switching Port
In case the mainframe host (FICON) is connected
with the CNT-made FC switch (FC9000 etc.), and is
using along with the TrueCopy S/390 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
(100ms) first, and then reset the Chip.
Mode 292=OFF (default):
When switching the port attribute, reset the Chip
without issuing the OLS.
