Disk Slot Numbers
To perform a disk hot-plug procedure, you must know the physical or logical device
name for the drive that you want to install or remove. If your system encounters a
disk error, often you can find messages about failing or failed disks in the system
console. This information is also logged in the /var/adm/messages files.
These error messages typically refer to a failed hard drive by its physical device
name (such as /devices/pci@1f,700000/scsi@2/sd@1,0) or by its logical
device name (such as c1t1d0). In addition, some applications might report a disk
slot number (0 through 3).
You can use the following table to associate internal disk slot numbers with the
logical and physical device names for each hard drive.
