Welcome to the unity memory module replacement demonstration. For more detailed instructions. I always referred to the applicable procedure on support dot ec dot com to begin, we're going to log into unisphere using the admin account. As we can see on the unity dashboard in the system health window, there are two hardware issues reported.
Click on the hardware icon to view more details. This brings us to the system view page here. We can see that memory module three of storage processor A or SP A needs attention. We could click on it or we can also navigate to the enclosure view for the disk processor enclosure and select the top view.
Now we can see that memory module three in P A is marked orange or faulted. Now, let's take a look at the alerts page. As we can see there are three alerts associated with this failure. Now that we have confirmed that it is memory module three and SP A let's start the replacement procedure.
We'll begin by navigating to the system service page and then select service tasks in order to replace a memory module for SP we must first put it in service mode, confirm that the enter service mode button for SP is highlighted and then click execute when prompted. Enter the service password entering service mode stops IO on the SP so that it can be safely removed.
Wait until the sp fault led is flashing alternating amber and blue before continuing to the next task. Here, we can see that SP A is in service mode. Also notice that the unsafe to remove led is illuminated on S PB. Make sure that you do not remove an sp with the unsafe to remove led illuminated. Begin by rotating the power cord retention, bail to the left and remove the power cord for SP A.
Make sure any network or IO module cables are labeled and then remove them. Do not remove any cables from S PB. Pull the torque limit screw handle out of the assembly and turn it counter clockwise to release from the as the handle is turned, the sp assembly extracts out of the enclosure.
When the outward movement stops, the sp assembly is ready for removal. Use the handle to pull the sp assembly outward enough to grasp the sides with both hands. Then with both hands supporting the SP assembly, pull the sp assembly out of the enclosure place the sp assembly with top side upward on a clean flat static free work surface.
Verify that all assembly LEDs are off to ensure that the SP has completed its power off after the removal from the D PE or disk processor enclosure. While pushing down the blue release button, slide, the top cover rear wood approximately one half inch until it stops. Lift the top cover upward and remove it from the SP.
Press in on the tabs on both sides of the airflow baffle, lift the airflow baffle upward and remove it from the SP assembly. Locate the memory module slot containing the faulty memory module or dim to press the two retaining tabs downward to free the memory module from its slot, touching only the module's outside edges align the replacement module with the connector firmly push the dim straight down into the connector.
When you hear a snap and feel the connector latches click into place. It is fully seated next align the two retaining clips on the airflow baffle with the slots on the side of the SP assembly and push downward on it to secure it to the sp position the top cover over the SP assembly and align it with the slots in the sides at the rear of the assembly, pull the top cover forward approximately one half inch to secure it in place.
Align the SP assembly with the enclosure slot and slide it into the slot until it stops, turn the orange torque limit screw handle clockwise until you hear a click sound from the handle. The click sound indicates the torque limit is reached and the SP assembly is seated fully in the enclosure. The SP will begin to boot into the service mode.
Push the orange torque limit screw handle into the SP assembly until you hear a click again. The click indicates the screw handle is secured in the assembly. Reconnect each IO module cable and network cable into the same port from which it was removed, connect the ac power cord to the power supply and secure the cord with the retention bail. Here, we can see that the SP is in the service mode with the sp fault led flashing, alternating amber and blue.
Now we can log back into unisphere to confirm the replacement. Now that we are logged back into unisphere. We can see we have some hardware issues. These are expected errors. Let's click on the hardware error to confirm here. We can see SP A and S PB are reporting errors. If we select SP A, we can see that it's reporting that it is in service mode.
If we click on S PB, we can see that it's reporting an unsafe to remove condition. Since these are both expected errors, we can now go back to the service task page and reboot sp A. This action will reboot sp A into normal mode. Select reboot for SP A and then click on execute when prompted, enter the service password note that it may take up to 20 minutes for the system to complete its reboot and return to normal after approximately 20 minutes log out and log back into unisphere to refresh the view.
Let's check the memory module status by navigating to the system view. Click on the enclosures tab and then select the top view. If we click on the memory module in slot three, we can see that it is operating normally. Now let's check the alerts page here. We can see the alerts associated with the memory failure in the replacement procedure.
After the initial alerts, we see the user executing the SP a service mode task. Then we see the user initiated sp reboot and finally ending with the storage system operating in normal mode to complete the memory module replacement task. We are going to acknowledge all the alerts associated with this action. This completes the unity memory module replacement demonstration.
