When looking at \doremi\log\kern.log (or \doremi\log\kern.log.x if the issue occurred a while
before the report was taken), the following message will NOT appear on the specific boot
that the RAID card was not detected:
Nov 12 10:07:10 ims1000 kernel: ata10.00: ATAPI: MARVELL VIRTUALL, 1.09, max UDMA/66
...
Nov 12 10:07:10 ims1000 kernel: scsi 9:0:0:0: Processor Marvell Console
1.01 PQ: 0 ANSI: 5
Note: This section is only applicable to IMS1000 units with the Marvell RAID card.
17.1.3 Solution
Contact Doremi Labs (Section 1.3) to replace the RAID card (Doremi PN: IMS-RAID-A2-AKI,
Manufacturer PN: DOR-IMSC-1RBP-1001
). For a temporary workaround, reboot the unit. It
may take several reboots before the unit if fully operational.
17.2 RAID Shutting Down
17.2.1 Description
RAID suddenly shuts down during correct operation or before any process occurs on the
system. Content is not seen, playback suddenly stops, and the /data and /opt status
indicators will be red and the storage details will be unknown in Monitoring → Diagnostics
→ Storage.
17.2.2 Identification
When looking at \doremi\log\kern.log (or \doremi\log\kern.log.x if the issue occurred a while
before the report was taken), you should see these kinds of messages when this issue
