The physical address of a hard drive is based on the slot in which it is installed.
If you are replacing a drive, ensure that you install the replacement drive in the same slot as the drive you removed.
If you are adding an additional drive, install the drive in the next available drive slot.
The procedures that you perform at this point depend on how your data is configured. You might need to partition the drive, create file systems, load data from backups, or have data updated from a RAID configuration.
The following commands might apply to your circumstances:
You can use the Oracle Solaris command cfgadm -al to list all disks in the device tree, including unconfigured disks.
If the disk is not in the list, such as with a newly installed disk, you can use devfsadm to configure it into the tree. See the devfsadm man page for details.
