Degraded State Of Virtual Disks

A redundant virtual disk is in a degraded state when one or more physical disks have failed or are

inaccessible. For example, if a RAID 1 virtual disk consists of two physical disks and one of them fails or

becomes inaccessible, the virtual disk becomes degraded.

To recover a virtual disk from a degraded state, you must replace the failed physical disk and rebuild it.

After the rebuilding process is complete, the virtual disk state changes from degraded to optimal.

General Issues

Shared PERC 8 Card Has Yellow Exclamation Mark In Device Manager

Issue: The device is displayed in Device Manager but has a yellow exclamation mark (!).

Corrective

Action:

Reinstall the driver. For more information on reinstalling drivers, see Driver

Installation. If reinstalling the driver does not resolve the yellow exclamation mark,

perform a shutdown of all server modules and power cycle the chassis.

Shared PERC 8 Card Not Seen In Device Manager

Issue: The device does not appear in the Device Manager.

Corrective

Action:

In the Dell Chassis Management Controller (CMC) application, verify if the Shared

PERC 8 is correctly mapped to the server module. For more information on

assigning virtual adapters to server slots, see the Dell Chassis Management

Controller for Dell PowerEdge VRTX User’s Guide at dell.com/poweredgemanuals.

NOTE: Make changes to Virtual Adapter to Server Slot mapping only when

the server modules are turned off.

If the Virtual Adapter to Server Slot mapping is correct and the device still does

not appear in the Device Manager, turn off the system and reseat the Shared PERC

8 card.
