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.

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.
