Physical Disk Slot Numbers, Physical Device
Names, and Logical Device Names for Non-RAID
Disks
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
c0t1d0
). In addition, some applications might report a disk slot
number (0 through 3).
You can use
to associate internal disk slot numbers with the logical and
physical device names for each hard drive.
