IBM System Storage Ideas Portal
This portal is to open public enhancement requests against IBM System Storage products. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).
Shape the future of IBM!
We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:
Search existing ideas
Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,
Post your ideas
Post an idea.
Get feedback from the IBM team and other customers to refine your idea.
Follow the idea through the IBM Ideas process.

We have also experienced a hardware (memory) issue that has gone unnoticed until someone physically saw the attention light on. In another instance, we found a node unbootable mid-code upgrade as it had a defective USB drive in the front panel.
Monitoring hardware is an expected feature to any enterprise storage device. Please implement this. In today's environments you can not expect equipment admins to be close to the equipment they manage.
During a random visit in the computer room, we noticed an amberlight on 2 SVC nodes. The SVC management interface did not report any error and we did not receive an alert.
We asked IBM to investigate and it appeared that a memory DIMM had failed or was about to fail. IBM couldn't provide information specifically what the issue was. We don't know how long this issue was present. We scheduled a maintenance window to replace the DIMM's.
If no one would have seen the LED, we only would have known when this DIMM problem really impacted the node by a crash.
SVC code should alert us via the usual error alerting that a node component needs to be replaced so that we can be proactive versus having a node crash and then suffering a longer outage of a node for repair.
Another consideration is that during a code upgrade, the node is rebooted. If the DIMM is marginal, the node may not complete the reboot and you are now doing a hardware replacement in the middle of a code upgrade.
To improve customer confidence on material reliability I think this "rfe" is really necessary. Thanks beforehand for your support
