Cause

"SCSI: Mode selector page" messages are generated in rare occurrences by a system incompatibility issue.

Resolution

A fix has been added to SGOS to resolve this issue:
  1. Power cycle the SG-S500-20 to clear the "SCSI: Mode selector page" messages and have the appliance boot normally
  2. Upgrade to SGOS 6.5.9.10 or later
  3. Upgrade to SGOS 6.6.5.1 or later
IMPORTANT: Symantec strongly recommends deleting all versions of SGOS that do NOT contain this fix.

NOTE: The " SCSI: Mode selector page" messages are software related and are NOT indicative of a hardware failure.

Workaround

Power cycling the SG-S500-20 will clear these messages and allow the appliance to boot normally.
