Prerequisites for removing the Shared PERC 8 Internal card

CAUTION: Many repairs may only be done by a certied service technician. You should only perform troubleshooting and simple

repairs as authorized in your product documentation, or as directed by the online or telephone service and support team.

Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions

that came with the system.

Perform the following steps to enable recovery in the event the part replacement process fails:

1 Follow the operating system procedure to back up all data from the shared storage drives

CAUTION: The part replacement procedure is complex and can put your data at risk if mistakes are made. It is imperative

that critical data is backed up prior to starting the procedure.

2 Document your virtual drive conguration and mapping information by performing the following steps:

a Open CLI terminal and run the command racadm raid get vdisks –o. Take a screen shot of the results page and save the

captured screen shot to a location of choice, or write down the information and store it in a safe, secure location.

b Click Chassis Overview → Storage → Virtual Disks → Assign to view the virtual disk mapping by the CMC GUI. Take a screen

shot of the results page and save the captured screen shot to a location of choice, or write down the information and store it in

3 Click Chassis Overview → Storage → Controllers to view the rmware version of the current Shared PERC 8 Internal card. If your

system has two Shared PERC 8 Internal cards installed, the rmware version must be the same for both the cards.
