Hello,
I am writing to express some frustration with a recent development utilizing our RAID attached to our Mac Pro (Trash Can)
Periodically, the RAID just hangs. You cannot launch a finder window. When you try, you get the spinning beach ball. The only way to recover when that happens is to unplug the RAID chassis and then reboot the mac. This is extra unfortunate because it's running in a lab about an hour from my home. With the Covid-19 thing, we are forced to work from home, but on these bad RAID days I have to drive to the office to physically reset.
This problem started immediately after updating the mac to Catalina as well as updating the RAID Chassis' firmware. The RAID array had been running on this machine prior for about 3 years flawlessly. This must have something to do with firmeware/Catalina update. I don't see any glaring disk errors (like a physical disk failing) in the logs.
Has anyone else experienced this?

Here is a link to my subsystem information
The array is the set of drives joined together. Inside the Disk Array, you can put one (or more) Logical Drives. The Logical Drives are what the Mac can detect. You are able to set the RAID level (0, 1, 1E, 10, 5, 6) when you create the Logical Drive.
A disk array's maximum size is (the number of drives) multiplied by (the smallest drive). So if you tell the Pegasus to make an array out of 6 drives, 5 of which are 3TB and one of which is 2TB, then the total will be 12TB (6 x 2TB).
If you take a physical drive out and replace it with a larger drive, the Pegasus R will rebuild to the original dimensions of the array* and you will not be able to take advantage of the larger size unless you delete the array and make a new array. Keep in mind the maximum array size will still be limited by the smallest drive in the array.
The best way to increase the drives is to backup your files to a second Pegasus or another storage medium; replace all the drives at once; create a new array over the larger drives; create a new logical drive to take up the new larger array; format that in Disk Utility; then restore your files from backup.
For more information please consult the Wikipedia articles on 'RAID' and 'Standard RAID Levels'. We would be happy to take your questions over the phone as well, at Promise Technical Support, 408-228-1500.

*Arrays containing RAID-0 logical drives cannot be rebuilt onto a blank drive, as they have no redundant data for the other drives to check. For this reason, the loss of any drive in a RAID-0 logical drive will take the logical drive offline.
