During backups, Symantec System Recovery Linux (SSRL) adds a disk signature on physical disks (/dev/sdX) that have no disk signature. Even if the backup job works successfully and the backed up disk has no problem, the applications that use the disks without disk signature may terminate unexpectedly, fail to start, or report some disk errors.
SSRL never replaces the existing disk signature on the physical disks.
A command to view the current disk signature on /dev/sdX is as follows.
# hexdump -s 4 -n 440 /dev/sdX
Red Hat 5.x / 6.x / x64 / x86
The issue does not depend on the distribution, version or architecture.
When there is no data (zero-padding) in 4 bytes from offset 440 (0x1B8) on the detected physical disks, SSRL adds the disk signature on them during backups.
