Valid for x86-64 systems only. Updates the list of alternate devices where system crash dumps can be written. This command does not create a dump file on any specified device; the recommended method is to use the CREATE command in the SYSGEN utility. If a specified device is not mounted or no dump file is found there, a warning will be output. The updated list of devices is saved in system memory for immediate use, and in the file SYS$MANAGER:SYS$DUMP_CONFIG.DAT for subsequent system reboots. Format SET DUMP_OPTIONS /DEVICE=(device[,...]) [/LOG]
1 – Qualifier
1.1 /DEVICE
/DEVICE=(device[,...]) /NODEVICE Specify the device(s) containing a system dump file SYSDUMP.DMP in the directory [SYSn.SYSEXE]. You can omit the parentheses when you specify only a single device. Only non-shadowed devices that are directly connected to the system can be specified (that is, neither MSCP-served nor shadow set units can be used). The previous contents of the list are replaced by the specified list. Use /NODEVICE to clear the list of alternate devices and only allow dumps to be written to the dump file on the system disk.
1.2 /LOG
/LOG Outputs informational messages
2 – Examples
1.$ SET DUMP_OPTIONS /DEVICE=DKA100: 2.$ SET DUMP_OPTIONS /DEVICE=$77$DKA200:/LOG %SET-I-FILEUPDATED, SYS$MANAGER:SYS$DUMP_CONFIG.DAT updated %SET-I-MEMUPDATED, memory settings updated 3.$ SET DUMP_OPTIONS /DEVICE=($77$DKA200:,DKA100:) In this example, DKA100: will only be used as a system dump device if $77$DKA200: is not accessible at the time of the system crash.
