Parity and disk1 have dropped offline. Check all connections power and SATA on all disks and post another diagnostic.

You're using a 2 port controller with two SATA multipliers, those kind of timeout issues are normal with those, I recommend you get an LSI HBA instead or you'll have constant issues.

You need a decent HBA, port multipliers will generally be nothing but trouble, get any LSI with a SAS2008/2308/3008 chipset in IT mode, e.g., 9201-8i, 9211-8i, 9207-8i, 9300-8i, etc and clones, like the Dell H200/H310 and IBM M1015, these latter ones need to be crossflashed.

I'm not saying the controller is the source of all your problems, but if you keep getting timeout errors similar to those on the diags you posted, the server will be unresponsive during those, and port multipliers are known to cause that.
