Operating Systems AIX Crash dump and Panic message : RSCT Dead Man Switch Timeout for HACMP; halting non-responsive node Post 303042369 by tomato00 on Sunday 22nd of December 2019 11:10:09 PM

Hi Neo and rbattel
my system are using GPFS(archive directory) and raw devices with Oracle RAC on the hacmp.

I think the reason why A-system has down itself is that B-system is down due to system bug and all oracle sessions of B-system node are moved to A-system, which causes huge IO on A-system. The sync time of the A-system was slowed down, and as a result, the system was down when the dead man switch limit was reached.

MOUNT_FILECORE(8)					    BSD System Manager's Manual 					 MOUNT_FILECORE(8)

NAME
mount_filecore -- mount a FILECORE file system SYNOPSIS
mount_filecore [-afnR] [-g gid] [-o options] [-u uid] special node ORIGIN
The NetBSD FILECORE filesystem is a read only implementation of the filecore file system found in Acorn Computers RISC OS operating system. This operating system is the ROM based operating system found on their ARM 6, ARM7 and StrongARM 110 based RiscPC machines that are supported by the arm32 port. Under RISC OS, filecore will have multiple instantiations for file systems on different block devices such as floppies, IDE discs, SCSI discs etc. and these frequently are considered to be different filesystems e.g. ADFS, IDEFS, SCSIFS etc. DESCRIPTION
The mount_filecore command attaches the FILECORE filesystem residing on the device special to the global filesystem namespace at the location indicated by node. Both special and node are converted to absolute paths before use. This command is normally executed by mount(8) at boot time, but can be used by any user to mount a FILECORE file system on any directory that they own (provided, of course, that they have appro- priate access to the device that contains the file system). The options are as follows: -a Give all files world access. -f Append the filetype to each filename. This option currently has no effect. -g gid Set the group of the files in the file system to gid. The default group is the group of the directory on which the file system is being mounted. -n Give all files owner access. -o options Use the specified mount options, as described in mount(8). -R Give all files owner read access. -u uid Set the owner of the files in the file system to uid. The default owner is the owner of the directory on which the file system is being mounted. SEE ALSO
mount(2), unmount(2), fstab(5), mount(8) HISTORY
The mount_filecore utility first appeared in NetBSD 1.4. CAVEATS
The 'filecore' filesystem currently supports the Acorn filecore file system found on Acorn Computers RiscPC desktop machines with versions of RISC OS up to 3.70. BSD
