My original question was:
We have a Ultra 10 running Solaris 7 with IDE disks. But, we have a 10GB
IDE disk that the system just recognizes 8 Gb. Is there patch to correct
it?
The answer is:
The disk was used in a Solaris 2.6, that just recognizes 8GB.
So, it needs to destroy the disk's label.
1. Make a backup.
2. Unmount the disk's partitions and comment out the disk 's partitions
in /etc/vfstab.
3. To destroy the label:
dd if=/dev/zero of=/dev/rdsk/c0t1d0s0 bs=1b count=16
where "/dev/rdsk/c0t1d0s0" is the raw device of the first partition.
Make sure this
information is correct.
This command wipes the first 16 512 byte block on the disk.
4. Reboot in single user mode.
5. Run format. You will see the warning about the wrong label of the
disk.
6. Choose the disk's number and create the partitions. The cylinder
offset may have changed. Partition 2 will need to map the entire disk
and gets bigger.
It is important that the new partitions (if you want to retain the data)
all have the exact smae size as before and start at the some block
offset.
7. Write the new label, using the "label" option at the partition
prompt.
