In order to gather needed information, we need to log onto Unisphere Manager on our VNXe. After we log in, we are presented with the management GUI. The GUI will generate alerts for failed components. We can investigate further by viewing the system health.
The System Health screen shows the severity of the error, as well as the problem component and description. Within the lower pane, we see the component description area. Here we need to make a physical note of the serial number and part number, as this will be needed when returning and ordering parts.
Once this information is gathered, choose Support > Need more help? > Customer Replaceable Parts and Order a Customer Replaceable Part. This will bring you to the Service Portal. You’ll need to log in using your support login account information. Within the Service Center, you will create a service record and generate a replacement order. This is where you’ll need the serial number and part number recorded earlier.
Follow the prompts and enter the information required to order the replacement part. Before you begin the replacement procedure, make sure you have correctly identified the faulted part and that a replacement module is available. Refer to your VNXe online help and official replacement procedures if necessary.
To protect your VNXe system from accidental data loss while you remove and replace DPE components, from the dashboard choose ‘Perform service operations.’ Log in with your service password. In the system components column, select the storage processor associated with the faulted component. Under Service Actions, select ‘Enter service mode,’ then ’Execute service action.′ The storage processor fault LED will flash alternating amber and blue while the SP remains in service mode. Caution: Do not remove a storage processor while the ‘Unsafe to Remove’ SP LED is on.
The light indicates that you may interrupt a vital system or data caching process. To remove the solid-state disk, you must remove the VNXe storage processor assembly. Disconnect the network power and any DPE DAE cables from the back of the storage processor assembly that includes the faulted SSD.
Do not remove any cables from the other storage processor assembly. Mark the network cables with the port numbers from which you remove them. Locate the two orange release levers on the bottom rear of the storage processor. On each lever, squeeze the latch knobs together to release the latches and then pull the latches outward.
Pull out the latches until they are fully extended and the storage processor assembly is released from the enclosure. Place the storage processor assembly on a clean, flat and static-free work area. The solid-state disk is located above and behind the I/O module enclosure in the storage processor assembly. Unlatch the solid-state disk by pinching the tab and then pulling the blue latch up.
Pull the solid-state disk out of the slot and set it aside on a clean, static-free surface. Unpack your new solid-state disk. Retain the packaging to return the faulted component. Slide the new solid-state disk into the slot on top of the storage processor. Close the latch. Make sure the latch snaps in place. Slide the storage processor assembly back into the chassis until it engages the enclosure and the latches start to close. Push the latch knobs into the assembly to seat it and secure it within the chassis. An audible click indicates the latches are in place.
Reconnect any cables you removed and be sure to use the power cord retention bail. Once you have replaced the faulted module and returned the storage processor assembly to the chassis, reboot the recently serviced SP. Under Service Actions, select ‘Reboot’ then ‘Execute service action.’ Note that it may take several minutes for the system to complete its reboot. Verify that the new module is recognized by your system and operating correctly.
In Unisphere, click ‘View system health.’ Select the storage processor if not already shown. In the component list, the replaced modules should be marked with an ‘OK’ status icon. In the graphical view, the module is highlighted green. Note, if the system health monitor shows the replacement module is faulted, contact your service provider. At this point, we can proceed to return the faulted module.
Choose Support > Need more help? > Customer Replaceable Parts > Return a Customer Replaceable Part. This will bring you to the Part Service Portal. You’ll need to log in using your support login account information. Once logged in, choose to process a return part using the supplied form. A return shipping label will be generated. Attach the shipping label to the return packaging and contact the appropriate person to pick up the faulted part.
