Solaris 10 installation fails with disk drive does not have a valid label.

When installing Solaris 10 I received this error.

This disk (c1t50060E800429C458d7) cannot be used to install
Solaris software.

This disk drive does not have a valid label. If you want to use
this disk for the install, exit the Solaris Interactive
Installation program, use the format(1M) command from the
command line to label the disk, and type ‘install-solaris’ to
restart the installation program.

I exited out of the installation and at the command prompt ran the format command. I then proceeded to label the drive, in this case it was a LUN (disk) sitting on a SAN. The LUN was connected via two fiber channel cards. I then ran the install-solaris command to continue with the installation, but ran into the same issue again. I decided to format the drive to see if it would help. I initiated the format command, the drive was 350G in size, I left it running over night and when I checked on the progress the next day it was still not completed. I killed the format of the drive and decided to call Sun suppport. While I was waiting for a call back I decided to check the internet for help. After much searching I finally found only one article, but thankfully it was the right one. It seems that there was a bug with the OS. If the disk drive was previously in a zpool with EFI label, then this would result in this error during installation. The LUN drive was indeed part of a zpool, I have been testing Solaris 10 zones on this drive with zpool and ZFS file system.

I decided to boot into Solaris, the version that was still installed on the drive and proceeded to delete the zpool and zones. But the drive failed again during the installation. The correct resolution was to run the format command with the -e option and then label the drive. The advance format mode allows you to change the EFI label to SMI. This should then allow you to install Solaris 10 on the drive.

Below is the screen shot for the format -e command.

# format -e

Note: Disk 2 (c1t50060E800429C458d7) and 3 (c2t50060E800429C448d7) are the same LUN on the Hitachi SAN. Because there are two paths to the LUN via two fiber channel interfaces, the same drive shows up twice. After Solaris 10 has been installed on disk 2, you can then enable multipath from the console prompt of the OS. You must be logged in as superuser to do this.

You can now continue with the installation of Solaris 10 again by running the command install-solaris.

# install-solaris
