Other than that, the system is running fine. I checked the /etc/rc.log file and the error is:<BR />SAVECORE: read failed /dev/dsk/c0t6d0 no such device<BR />SAVECORE: error reading dump header<BR />Exit code 1<BR />"sbin/rc1.d/s440Savecore start" failed.<BR /><BR />It mentions that device /dev/dsk/c0t6d0 is not there but it is the boot drive and is operating okay. Although it is not causing a problem at this time, does someone know how to fix this?<BR /><BR />Thanks,<BR />Ken Smith Tue, 20 Nov 2001 03:24:57 GMT https://community.hpe.com/t5/operating-system-hp-ux/core-image/m-p/2617290#M37856 Kenneth Smith 2001-11-20T03:24:57Z https://community.hpe.com/t5/operating-system-hp-ux/core-image/m-p/2617291#M37857 you probably had a system panic and crash..<BR />figure out why with /etc/shutdownlog<BR /><BR />Then to fix your dump.. see the following:<BR /><BR />lvlnboot -v<BR />output<BR /><BR />you may have to define the dump device to be the lvol2 for example.. ie swap space. on reboot the core will be saved in /var/adm/crash.<BR /><BR />man lvnboot for details.<BR /><BR />Later,<BR />Bill<BR /> Tue, 20 Nov 2001 12:10:39 GMT https://community.hpe.com/t5/operating-system-hp-ux/core-image/m-p/2617291#M37857 Bill McNAMARA_1 2001-11-20T12:10:39Z
