PROBLEM DESCRIPTION:
On Sun Ultra 5/10 workstations, use of the following shutdown(1M)
command 'shutdown -y -i5 -g0' might result in the IDE disk drive not
getting "sync'ed" properly. If the disk is not "sync'ed" (see
sync(1M))
properly, "Uncorrectable data Errors" are reported which may lead to
unnecessary disk replacement.
Failing Configuration: Ultra 5/10 systems with internal IDE drives.
Here are two different cases of error messages which may be seen in the
/var/sadm/messages files upon boot up after using the shutdown -y -i5
-g0 command:

NOTE: In some cases, the fsck(1M) command may need to be run manually
to repair file systems when the system is booted. But in most
cases fsck activation during reboot.
Unlike SCSI disks, IDE drives have their internal write cache enabled.
Whenever the system is powered down, the data in the disk cache is not
flushed causing possible data corruption.
The fix requires writing a new entry point in the IDE driver that will
send a disk flush command before powering down the disk.
IMPLEMENTATION:
---
| | MANDATORY (Fully Pro-Active)
---
---
| X | CONTROLLED PRO-ACTIVE (per Sun Geo Plan)
---
---
| | REACTIVE (As Required)
---
CORRECTIVE ACTION:
The following recommendation is provided as a guideline for authorized
Enterprise Services Field Representatives who may encounter the above
mentioned problem.
The recommended workaround is to use the "-i0" option instead of the
"-i5" option for shutdown:
# shutdown -y -i0 -g0
Please install the following patches as a final solution:
---------------------------------------------------------
| Solaris | Solaris patchId | IDE PatchId |
|=========================================================|
| 2.5.1 | 103640 (or later) | 106197 (or later) |

| 2.6 | 105181 (or later) | 106407 (or later) |
|---------+------------------------+----------------------|
| 8 | 108528 (or later) | 108974 (or later) |
---------------------------------------------------------
NOTE: For Solaris 7, patch numbers are not yet available.
COMMENTS:
There have been cases in the field that the disk drives were
inadvertently replaced.
The boot disk is less prone to data loss as this is not used normally
to store user data. But any other internal IDE drives could cause
substantial damage to the customer as data perceived by applications to
have been written to the disks are lost.

Implementation Footnote:
________________________
i) In case of MANDATORY FINs, Enterprise Services will attempt to contact
all affected customers to recommend implementation of the FIN.
ii) For CONTROLLED PROACTIVE FINs, Enterprise Services mission critical sup-
port teams will recommend implementation of the FIN (to their respective
accounts), at the convenience of the customer.
iii) For REACTIVE FINs, Enterprise Services will implement the FIN as the need
arises.
