Problem
"Corrupt label; wrong magic number" message appears in the Solaris syslog (/var/adm/messages)
Error
Jul 30 17:14:13 sinatra2 Corrupt label; wrong magic number
Jul 30 17:14:13 sinatra2 scsi: [ID 107833 kern.warning] WARNING: /pci@8,600000/fibre-channel@2/sd@14,1d (sd162):
Solution
This is a message that the operating system displays if a
disk has no label on it. Labels are written to the Volume Table of Contents
(VTOC) in the first block of the
disk.
Cause:
Cause:
- This happens when a new disk is presented to the host and the host has not run the format() command to write this label
- This is normal to see when a new disk has been freshly created and presented to the operating system
- This can be reported if a healthy disk is written to in a non standard manner where the VTOC has been destroyed with a command such as dd()
Resolution:
1. Run the format() command and choose the disk from the menu. This will label the disk.
2. Run the fmthard() command in a situation where there are many disks and a script should be employed
Note: This could be detrimental to restoring data. Check with your technical experts if critical data is involved since this action could cause a negative impact on attempts to restore lost data.
