Sun Fire 280R, V480, and V880 With Solaris 9 and MAN3735FC or MAP3735FC 72GB Internal Drives May Repeatedly Log SCSI Warnings

---

Impact

On Sun Fire 280R, V480 and V880 Systems running Solaris 9, SCSI error messages will be generated when SunMC issues a "CDB 0x46" command to fixed disks that are non-Multi-Media Capable (MMC) devices (this command being honored only by MMC capable devices, based on SCSI standards). The "config-reader" periodically generates these error messages while inquiring the status of the disk, which may adversely affect system monitoring efforts.

Contributing Factors

This issue can occur in the following releases:

SPARC Platform

• Solaris 9 without patch 113277-19

and on the following platforms:

• Sun Fire 280R, V480, V880

Notes:

1. Solaris 7 and 8 are not affected by this issue.
2. To date, the descibed issue has been observed only on the Sun Fire V880. Sun Fire 280R and V480 also support the MAN3735FC and MAP3735FC 72GB Internal drive type and are susceptible to this issue.

To determine if a Sun system contains the affected drive type (MAN3735FC or MAP3735FC 72GB), run the format(1M) command as "root" user and use the "inquiry" command from the format menu to determine a disk's type, as shown in the following example:

    # format
    Searching for disks...done
        AVAILABLE DISK SELECTIONS:
                0. c0d0 <DEFAULT cyl 611 alt 2 hd 16 sec 38>
                   /pci@19,700000/pci@3/SUNW,isptwo@4
                1. c1t1d0 <DEFAULT cyl 1463 alt 2 hd 9 sec 64>
                   /pci@18,700000/pci@3/SUNW,isptwo@4
        Specify disk (enter its number): 1
        selecting c1t1d0
        [disk formatted]
        FORMAT MENU:
               disk       - select a disk
               type       - select (define) a disk type
               partition  - select (define) a partition table
               ...
               inquiry    - show vendor, product and revision
               volname    - set 8-character volume name
               quit

         format> inquiry
         Vendor:   <NAME>
         Product:  MAN3735F SUN72G
         Revision: 0704

         format> quit

Symptoms

When SunMC (config-reader) issues a "CDB 0x46" command (SCMD_GET_CONFIGURATION) to a MAN3735FC 72GB or MAP3735FC drive, the drive returns an "Illegal Command" error. Every 5 minutes (or so) when the config-reader is scheduled to run, the following error messages are output to "/var/adm/messages":

    FCP: WWN 0x500000e01011b371 reset successfully
