Description
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.
Tru64 (Host Mode 07) and OpenVMS (Host Mode 05)
Caution: Host offline: Required
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 1 14=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.
This mode enables the pre-label function (creation of VTOC
including VOLSER).
Mode 305 = ON:
Pre-label function is enabled
Note:
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
<Description>
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 newly assigned system
option Mode as individual function for specific customer.
Usage:
Mode 308 = ON
SIM RC 2180 is reported which is compatible with older Hitachi
specification
Mode 308 = OFF
Reporting is compatible with IBM - Sense Status report of F5.
