Mode Category Description Default MCU/RCU
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.
OFF MCU/RCU
305 Mainframe This mode enables the pre-label function (creation of VTOC
including VOLSER).
Mode 305 = ON:
Pre-label function is enabled
Notes:
1. Set SOM 305 to ON before performing LDEV Format
for a mainframe volume if you want to perform OS
IPL (volume online) without fully initializing the
volume after the LDEV Format. However, full
initialization is required in actual operation.
2. Processing time of LDEV format increases by as much
as full initialization takes.
3. The following functions and conditions are not
supported.
• Quick format
• 3390-A (Dynamic Provisioning attribute)
• Volume Shredder
4. Full initialization is required in actual operation.

SIM RC=2180 option
SIM RC=2180 (RIO path failure between MCU and RCU)
was not reported to host. DKC reports SSB with F/M=F5
instead of reporting SIM RC=2180 in the case. Micro-
program has been modified to report SIM RC=2180 with
