Removing the processor card

Complete this task to remove the processor cards from the server enclosure or the expansion enclosure, either when the system is powered off or powered on.

Use approved ESD procedures to prevent damage.

Before you remove the processor card, you must ensure that the error indicator is lit. If the error light is not lit on the processor card, you must first go to the DS Storage Manager and take the processor card offline. You must also ensure that you have a replacement processor card.

Removing and replacing a processor card might result in the following effects:

Removing a processor card that does not have a solid amber error indicator lit causes performance degradation and loss of access to data.
Note: Removing a processor card that has a solid amber error indicator does not have any effect on the operation of the storage unit.
If, while the first processor card is removed, the second processor card fails, the enclosure will lose configuration settings and access to the data. Data loss might occur if certain processes were occurring at the point of failure.
Removing a processor card will cause loss of access to host systems if multiple paths from the storage unit to the hosts are not configured.

For these reasons, you must remove and replace only one processor card at a time. The processor card that stays in the enclosure retains the configuration settings and transfers the configuration information to the new processor card once you replace it in the enclosure. The time that is required to transfer the configuration settings depends on network connectivity, I/O traffic, and other factors.

Important: When you are removing a processor card from an enclosure, ensure that all resources from a particular server or expansion enclosure are reinstalled into the same physical enclosure and in the same location inside that enclosure. Record the locations of the fiber optic cables and the Ethernet cable so that you can remember their original locations.

After you remove the processor card from the enclosure, wait a minimum of 2 minutes before you replace the card.

The processor cards are located in the rear of the expansion enclosure. One of the cards is located below the rear operator panel and above the battery backup units. The other card is located below the battery backup units and above the system service card.

In the case of a dual processor card replacement, you must replace the processor cards one at a time to ensure that at least one processor card is always operating in the enclosure. After you replace the first processor card, wait until you can access the enclosure using the DS Storage Manager before you remove and replace the second processor card. Do not remove both processor cards at the same time.

Press the orange release button. This releases both handles.
Grip both handles, one with each hand.
Pull both handles out and towards the outside of the enclosure. The right handle pulls out and to the right of the enclosure. The left handle pulls out and to the left of the enclosure. This partially ejects the processor card from the slot.
Use the handles to pull the processor card partially out of the slot.
Grip the processor card with both hands to pull the resource completely from the slot.
