Certain Disk Drives May Experience Data Miscompare or Drive Initialization Issues

1. Impact

Certain disk drives with disk firmware version SU0B may experience data integrity issues or drive intialization failure. There are two possible conditions associated with these drive firmware Bugs:

A. Disk drives may experience data miscompare errors, potentially affecting data integrity.
B. The affected drive may fail to initialize (hang) following power initialization and may not be visible to the system.

2. Contributing Factors

These issues can occur on the following disk drives:

• ST32502NS (250.0GB) SATA Disk Drive (390-0411-02, 390-0411-03)
• ST35002NS (500.0GB) SATA Disk Drive (390-0412-02)
• ST37502NS (750.0GB) SATA Disk Drive (390-0413-02)
• ST31000NS (1.0TB) SATA Disk Drive (390-0414-02)

with firmware version SUOB and without firmware version SU0D, for the following platforms:


To determine the firmware revision on the drive, run format(1M) with 'inquiry', as in the following examples:

either of the above examples indicate the drive firmware revision is SU0B and requires upgrade to SU0D.

Alternatively, drives can be inspected visually for the Sun model number (as listed in Contributing Factors).

3. Symptoms

The data miscompare issue will not produce any visible symptoms and will not be detected by the drive or the host.

For the drive hang issue, the affected drive may fail to initialize following power initialization and may not be visible to the system.

4. Workaround

There is no workaround or avoidance for the data miscompare issue.

To avoid the drive hang issue, limit the number of power cycle events to the system until drive firmware can be upgraded.

5. Resolution

These issues are addressed in the following release:

• Firmware SU0D (as delivered in patch 140698-01 or later) for the following drives:

• ST32502NS (250.0GB) SATA Disk Drive (390-0411-02, 390-0411-03)
• ST35002NS (500.0GB) SATA Disk Drive (390-0412-02)
• ST37502NS (750.0GB) SATA Disk Drive (390-0413-02)
• ST31000NS (1.0TB) SATA Disk Drive (390-0414-02)

for the following platforms:


To address this issue for ST31000NS (1.0TB) drives in J4200/J4400 arrays only, two CAM patches must be installed (platform update first followed by firmware update) due to dependencies between the platform and firmware carried forward from the -01 version of these patches. In order for the two patches to be installed, CAM must be running (or upgraded to) version 6.2 (or later) and can be downloaded from:

http://www.sun.com/download/index.jsp?cat=Systems%20Administration&tab=3&subcat=Storage%20Management

followed by application of the folllowing CAMS patches:

• for Solaris:140060-02 (or later) and 140064-02 (or later)
• for Linux: 140062-02 (or later) and 140065-02 (or later)
• for Windows:140061-02 (or later) and 140066-02 (or later)

Installation of these patches will vary for each OS, and instructions can be found in the README file of each patch.  Shortly after these patches are installed, CAM will generate an alarm which will guide the admin through the upgrade process when desired.

If the J4400 is used as part of Sun Storage 7310/7410, upgrade to the latest appliance software image, which can obtained from:


The disk drive firmware is included and will be upgraded automatically.

Note: Although the probability of occurrence for either condition is low, it is highly recommended that drive firmware be upgraded for all affected disks, regardless of system.

Notes:
for the data miscompare issue:

The drive may return incorrect data from the cache instead of the
requested data if it receives a read
command for a logical block that is in the process of being written to
the disk as a part of a write operation that extends across a large
range of consecutive blocks which includes the read command block (The
drive should not have responded to a read command for a block
prematurely while write operations are pending or in progress for that
block).

for the drive initialization
failure issue:

After the drive Critical Event Log is full, the pointer gets confused
during initialization tests causing it to fail on a subsequent power
cycle. If the drive 'Event Log' is at the last index in its circular
buffer,the drive may fail to come into a ready state if the system is
power cycled. Drive Firmware cannot be loaded on to the drive once the
drive is in this state.
Sun is currently purging all inventory from manufacturing (WIP, Raw
Stock & inTransit) except Finished Goods and all FRUs, x-options at
service and at Sun Stock, for rework to be upgraded to the new
firmware. The firmware has been released with ECO, WO_40835.
