CAM status: SCSI Status Error in dmesg

[mosh]

Hello,
Today i experienced my first glitch of the freeNAS storage (FreeNAS-9.10.2-U4)
I noticed the following error in dmesg, and I want to ask your assistance on how to extract the most valuable information from it

such as:
Does that means that da0 disk experienced write failure, how can i test the disk (ssd)? should i consider replacing it?

Code:

(da0:mps0:0:0:0): WRITE(10). CDB: 2a 00 98 c0 74 b8 00 00 18 00 length 12288 SMID 634 command timeout cm 0xfffffe0001724020 ccb 0xfffff81fd8297000

from the following line i understand the LSI unit was reset or the bus reset, but how can I know which happened?

Code:

(da0:mps0:0:0:0): SCSI sense: UNIT ATTENTION asc:29,0 (Power on, reset, or bus device reset occurred)

How can I check its condition?

Code:

(da0:mps0:0:0:0): SCSI status: Check Condition

Thanks for your comments

In the GUI, is the disk listed as online or not?
Usually, seeing something like this indicates that the disk has failed, but it could be a wiring issue. As it says, check that the disk is present, healthy, online, etc. Find out things about the disk and let us know what you have found.
