You can install a pair of cache memory
upgrades while the Lenovo Storage V3700
V2 XP, Lenovo Storage V5030, or Lenovo Storage V5030F system is operational.
A Lenovo Storage V3700
V2 XP system can be upgraded to 16 GB of memory. Lenovo Storage V5030 and Lenovo Storage V5030F systems can be upgraded to 32 GB of memory.
Notes:
- When a canister is missing, operate the enclosure for as little
time as possible. When a canister is missing, the airflow in the enclosure
is disrupted. As a result, the system can overheat if it is left that
way for too long.
- Memory modules are susceptible to electrostatic discharges.
- If you add extra RAM for an I/O group that is using
compression, you must complete a warm start on both nodes in the I/O
group for the changes to affect compressed I/O.
Complete the following steps to install a pair of options
while the system continues to perform I/O operations.
- In the management GUI, check the Recommended Action event log view. Resolve any issues
before you continue the procedure. Remove one node canister from the
cluster.
- Remove the lid from the canister.
- Locate memory slot 2, which is next to the
battery, under a large heat sink (Locating the memory slot).
Figure 1. Locating the memory slot
- Open the retaining clip on each end of the DIMM connector.
Attention: To avoid breaking the retaining clips
or damaging the DIMM connectors, open and close the clips gently.
- Touch the static-protective package that contains the DIMM
to any unpainted metal surface on the outside of the canister.
- Remove the DIMM from the package.
- Turn the DIMM so that the DIMM keys align correctly with
the connector.
- Insert the DIMM into the connector by aligning the edges
of the DIMM with the slots at the ends of the DIMM connector. DIMMs
do not stand up; rather, they lie in a cascading fashion (Inserting the DIMM into the memory slot).
Figure 2. Inserting the DIMM into the memory slot
- Firmly press the DIMM straight down into the connector
by applying pressure on both ends of the DIMM simultaneously.
The retaining clips snap into the locked position when
the DIMM is firmly seated in the connector.
Note: If there is a gap
between the DIMM and the retaining clips, the DIMM is not inserted
correctly. Open the retaining clips, remove the DIMM, and reinsert
it.
- Reinstall the lid on the canister.
- Reinstall the canister in the enclosure
and replace cables that were removed.
Do not attempt to restart any host systems until instructed
to do so.
The canister restarts. Because the hardware configuration
changes, a node error (841) and associated alert (1199) are recorded
in the system event log.
- Use the Recommended Action in the management GUI monitoring page to check and accept the hardware changes.
The node canister restarts as part of this process. When
the system restarts, an alert 1470 indicates that the node canister
hardware does not match. You can ignore this alert.
- Wait 30 minutes for failover to occur.
- Repeat steps 1 to 12 for
the second canister.
Verify that host systems have rediscovered the first canister
so they can fail over it when the second canister is removed.
- Restart any host applications that you stopped earlier.
After the mismatched hardware error 1470 has automatically
cleared, both nodes are successfully running with the additional RAM.
- Use the Recommended Action in the management GUI monitoring page to complete the system update procedure.
- Check for any new alerts in the event log. Resolve them
using the information in Recommended Action.
- Run the chnodecanisterhw command on each canister to update the hardware configuration.
