Judging by this output, it appears the the Linux kernel on your SLES11
system sees different VTOC data than the kernel on SLES10. Please try
the following:
- Set the device offline on both systems
- Detach the device from both systems
On the SLES10 system:
- Attach + set online
- Check if the partition is recognized
- Dump VTOC data:
dasdview -t all /dev/dasd... >sles10.txt
- Set offline + detach
On the SLES11 system:
- Attach + set online
- Check if the partition is recognized
- Dump VTOC data:
dasdview -t all /dev/dasd... >sles11.txt
- Compare the VTOC data:
diff -u sles10.txt sles11.txt
If there is a difference, please send the output of the diff command.
