Symptom

INIT: version 2.86 booting Welcome to PanOS INIT: Sending processes the TERM signal Stopping PAN Software: [ OK ] Shutting down NFS mountd: [ OK ] Shutting down NFS daemon: nfsd: last server has exited, flushing export cache [ OK ] Booting 'PANOS (sysroot0, sda)' root (hd0,1) Filesystem type is ext2fs, partition type 0xfd kernel /boot/vmlinuz ro root=/dev/md2 console=ttyS0,9600n8 quiet Error 15: File not found Booting 'PANOS (sysroot0, sdb)' root (hd1,1) Filesystem type is ext2fs, partition type 0xfd kernel /boot/vmlinuz ro root=/dev/md2 console=ttyS0,9600n8 quiet Error 15: File not found Press any key to continue...
Environment
- Palo Alto Firewall
Cause
This specific problem may be caused when a user sets the RAID master as one drive, interrupts the process, and then setting the other drive as the master.
The result is that both partitions have their kernel file pointers (vmlinuz) renamed by appending “.saved”.
During the boot process, the system looks for the pointer named “vmlinuz”.
In this case, the pointer does not exist and thus, the system fails to boot with "Error 15".
Resolution
