WARNING: Some or all of the metadata stored on map disks lacks redundancy.
The amber light of the VA is also up.
The engineer said that the faulty disk is one of the disk to stores the "Recovery Maps" within the VA. He claimed the Recovery Maps has been already sync, but the Warning message is not cleared. He said the VA needs power recycle to clear the Warning message.
As we expect VA is a high availability storage and single disk failure should not introduce any service break. I would like to ask is it normal to power recycle if a "Recovery Maps" disk failure? And is it possible to clear the warning online without reset the VA.
Thanks
Solved! Go to Solution.

SolutionI suspect there already were some structures on the disk and that's why your VA did not write its maps onto it.
I suggest the following (have a backup before doing it - to be on the safe tack):
1. fail M/D2 'armcfg -D M/D2 -d -F va05phq'. This command should work without problems because there's enough space for rebuild;
2. VA will start rebuilding. Watch 'armrbld -p va05phq' and proceed to step 3 as soon as it will finish (estimated time: 3 hours);
3. unfail and include disk into VA disk set 'armcfg -D M/D2 -a va05phq'.
I hope it will help

Re: VA7100 Warning: metadata lacks redundancy
The engineer finally suggested to replace the disk again with a new unformatted disk. He claimed that the replacing disk was formatted before. I think the reason is similar to your finding.
By the way, I am amazed that how Eugeny familiar with storage. As I am newbie to VA and SAN, I am not familiar with many commands of VA operation.
Eugeny, would you mind to share some experience of storage support?
