Notes:
(1) For HUS VM, this mode is applied to use scripts etc that
are used on Lightning 9900 and Lightning 9900 V.
(2) Executing the pairresync command from RAID Manager
may be related to the System Option Mode 087 setting.
(3) When performing At-Time Split from RAID Manager,
Set this mode to OFF or specify the environment variable
HORCC_SPLT for Quick.
Otherwise, Pairsplit may turn timeout.
(4) The mode becomes effective after specifying Split/
Resync following the mode setting. The mode function does
not work if it is set during the Split/Resync operation.
292
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 (100 ms)
first, and then reset the Chip.
Mode 292=OFF:
When switching the port attribute, reset the Chip without
issuing the OLS.
OFF
310
Mode 310 = ON:
The monitoring timer for MP hang-up is 6 seconds and
returning a response to the host within 8 is guaranteed.
Mode 310 = OFF:
The monitoring timer for MP hang-up remains 15 seconds
(USP/NSC / USP V/VM) or 8 seconds (VSP/ VSP G1000).
Notes:
(1) This mode applies to a site where strict host response
performance is required.
(2) If a hardware failure occurs when the mode is set to ON,
the time until MPB blockage is determined is shorter than
usual.
OFF
448
Mode 448 = ON: (Enabled)
If the SVP detects a blocked path, the SVP assumes that an
error occurred, and then immediately splits (suspends) the
mirror.
Mode 448 = OFF: (Disabled)
