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.
Notes: 
1. For more details about mode 269, see 
worksheet "Mode269 detail for RAID700".
2. Mode 269 is effective only when using the SVP 
to format the CVS.

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.
