The CIPCA, CIXCD, KFMSB, and Qlogic 1020ISP adapters are some of the adapters that use bus-addressable pool to improve performance. BAP is a non-paged dynamic, physical-address-filtered memory pool used to overcome I/O bus and 32-bit adapter physical addressing limits. The following table lists the system parameters that control BAP operation along with their default values: The default values of these parameters allow the system to boot with any configuration.TOGEN is em fails to boot after an installation, upgrade, or configuration change, and displays a message that refers to incorrect BAP parameters, HP recommends that you perform the following steps:
1. Reset the BAP parameters to the default values.
2. Allow the installation procedure to run AUTOGEN, or manually run AUTOGEN yourself.
A typical AUTOGEN with FEEDBACK command to set these parameters follows:
$ @SYS$UPDATE:AUTOGEN SAVPARAMS SETPARAMS FEEDBACK
NOTE These parameters are critical. HP recommends that you run AUTOGEN as describedset correctly. If you prefer not to use this command because you want to adjust only the BAP parameters settings, use the following procedure: ually run SYS$SYSTEM:AGEN$FEEDBACK.EXE:
$ RUN SYS$SYSTEM:AGEN$FEEDBACK.EXE
Search SYS$SYSTEM:AGEN$FEEDBACK.DAT for the BAP_* system parameter values:
$ SEARCH SYS$SYSTEM:AGEN$FEEDBACK.DAT "BAP_"
Run SYSGEN to set the following system parameters with the BAP values you obtained in the step before
Managing System Parameters amount (specified by BAP_MIN and BAP_MAX) depends on the adapter type, the number of adapters, and the version of the operating system. The physical address range (specified by BAP_MIN_PA and BAP_MAX_PA) depends on the adapter type and the way the Galaxy logical partitions, if any, are defined.
NOTE If you manually set parameters NPAG_BAP_MIN_PA and NPAG_BAP_MAX_PA, be sure to specify the value for each parameter in the correct units (bytes or megabytes) for your operating system version.
On OpenVMS Alpha systems prior to Version 7.2, the value of this parameter is specified in bytes.
