73GB Internal Disk Drives In Sun Fire V480/V880 System May Go Offline When Used In Dual Loop Configuration

---

Impact

Sun Fire V480/V880 with MAN3735FC (73.4GB) FC-AL internal disk drives in dual loop configuration may go offline, report transport errors and stop reporting I/O to both loops on the system due to a disk drive firmware issue.

Contributing Factors

This issue can occur on the following platform:

SPARC Platform

• Sun Fire V480/V880 with Internal Disk Drive MAN3735FC (73.4GB, FC-AL) without patch 116513-01

Notes:

1. Both Sun Fire V480 and V880 platform utilize this drive type in dual-loop configuration.
2. This issue only occurs with the drive in dual loop configuration.
3. Please use the Sun System Handbook for further details on this product at http://sunsolve.sun.com/handbook_pub/Systems/SunFire880/components.html#DISK

To determine if a Sun Fire V480/V880 system contains this drive type, do one of the following:

A. If the system is down, run the "probe-scsi-all" command from the "ok" prompt:

    ok> probe-scsi-all
    /pci@19,700000/pci@3/SUNW,isptwo@4
    /pci@18,700000/pci@3/SUNW,isptwo@4
    Target 0
       Unit 0   Disk     <NAME> MAN3735FC SUN72G
    Target 1
       Unit 0   Disk     <NAME> MAN3735FC SUN72G
    ...
    ok>

B. If the system is up, run the "format" 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

Note: Both Revision 0604 and 0704 are affected by this issue.

C. If Explorer has been run on the system, the drive type will be captured in the file "/opt/SUNWexplorer/bin/diskinfo".
