Finding a Physical Disk

Disk Storage Management 4-27

Finding an External Physical Disk

For disks in external storage systems, the operating system assigns letter designations

to the logical volumes on the physical disks. Windows Disk Management assigns a disk

name to each physical disk in an external storage system and displays which logical

volumes reside on each named disk. For a particular volume, you can use the disk

name in conjunction with ftSMC to identify the location of the physical disk that contains

that volume.

NOTE

The disks of EMC storage systems do not appear in

ftSMC.

To find a volume’s physical disk

1. In the Windows Disk Management tool (accessed from My Computer), find the

disk name that contains the volume in question. These disk names may or may not

be numeric; however, they do not correspond to disk locations. Volume information

is displayed along with the disk name.

2. Note the disk name that contains the volume you want to physically locate; for

example, Disk 3.

3. In ftSMC, expand Storage Enclosures, then Logical Disk Information, and then

click Logical to Physical Mapping.

4. In the Name column of the ftSMC details pane, find the disk name you noted in

step 2. Look up its corresponding device path ID in the Value column. This

identifies the physical location of the disk within the system. (See “Device IDs and

Device Paths” on page 5-6 for details.)

For example, Disk 3 may have the disk name Harddisk3 in ftSMC and have a

device path ID of 70/12/3. This disk would appear in ftSMC under the Storage

Enclosures node as Disk 3 in Slot 12 of Storage Enclosure - 70.

5. Use the device path ID determined in step 4 with the labels on the system to identify

the disk location. You can also use “Diagrams of Component Locations” on

page 5-8 to help locate the disk.

NOTE

When external disks are resynchronizing, the Logical to

Physical Mapping details pane shows the disk that is

resynchronizing as SIMPLEX and includes the

percentage of the disk that has resynchronized: for

example, SIMPLEX (%20).
