Dell poweredge VRTX - Installing and Setting Up the CMC

4 Troubleshooting
4.1 Shared PERC 8 External cards fail to function
Issue:
Shared PERC 8 External cards fail to function in systems with the Fault Tolerant Shared PERC 8 external
card configuration.
Corrective Action:
This issue may occur if the Shared PERC 8 external card property settings between the two Shared PERC 8
external cards are not compatible. Ensure that the firmware packages are identical for both the Shared
PERC 8 external cards.
4.2 EMM failure message seen after EMM firmware update
Issue:
CMC displays error message immediately after an enclosure update that the EMM has failed.
Corrective Action:
After an EMM update, turn off and restart the VRTX chassis.
4.3 Incorrect number of virtual disks displayed in Windows Disk
Manager
Issue:
The number of disks displayed in Windows Disk Manager is more than the actual number of virtual disks
assigned to the server.

This issue occurs if the MPIO feature is not installed in systems with the Fault Tolerant Shared PERC 8 card
configuration. Install MPIO services from the list of features that can be installed on the server. For
instructions on how to install MPIO, see Installing and Configuring MPIO at technet.microsoft.com.

of data. Perform the following steps to recover the virtual disk:
Caution: Follow the safety precautions to prevent electrostatic discharge.
1. Turn off the system, check the cable connections, and reseat the physical disks.
