Strange problem - all information from the storage tab disappeared. After that, vCenter lost connection with all hosts. The connection was lost gradually, the connection to each host dropped one every 10 minutes. Thus, we lost control of the entire cluster in ~30 minutes. Never seen anything like this before.
But At the same time, everything seems to be working, the hosts are available, the storage seems to be available too.
Have no idea what's happened...Your response on this will be highly appreciated. Thank you!
I assume 0B28470; from the internal part search and it returned HDD, 1.2TB, 512b, SAS6, 10K RPM, 2.5 inch, 64MB, Hitachi. I read the first post, you mentioned while the issue occurs, "everything seems to be working, the hosts are available, the storage seems to be available too.". And from the error that you provided, I will say it's an issue that CMC and SPERC unable to communicate.
Here's what I can suggest, is to reboot the CMC. Generally rebooting the CMC will not affect the server overall usage. But make sure there is no occuring updates in progress. If the issue persist, check for CMC firmware version, if it's outdated, you may need to update it. Then check SPERC's firmware too.

Hello! thank you for your answer. We have only one CMC, so we can't do a failover...
But i have one thought - we changed 2 faulty disks to new ones, after which the following situation arose; on the weekend we changed the controller, it entered into operation, the storage field filled up, after which it showed that another disk was in the "faulty" state. VRTX worked for another day, after which the same situation arose again as in the previous post. Could it be the new disks? and if we remove them, can we restore normal operation of the system?
When you encounter this issue, is there any CMC log trace showing "CTL96 RAID Controller in Chassis Slot 6 has entered safe mode with limited functionality"? - The logs will be shown in the CMC logs not the storage event logs page like the screenshot.
The picture of the 1st post looks almost similar like the SPERC goes into safe mode. This can be caused by failed disk, pinned cache or SPERC cabling. I saw the controller count in your screenshot is showing only 1 SPERC, so I'm assuming there isn't 2 SPERC for fault-tolerant configuration. You mentioned there is a failed disk, have you resolved it by replacing it?
