Purpose
Scope
VTL - What are the meanings of the hardware compression/decompression driver error codes
Applies to:
Sun StorageTek VTL Plus Storage Appliance - Version: 2.0 - Build 1656 to 2.0 - Build 1656 [Release: 2.0 to 2.0]
Sun 386i Sun/OS

Purpose
This article provides the meaning of error codes from the HiFN hardware compression/decompression driver as used in Sun VTL Plus 2.0 servers.
Scope
The Sun HiFN compression driver as used in the Sun VTL Plus 2.0 server provides return error codes in the /var/adm/messages file to report problems with compressing and decompressing blocks for the VTL software.
VTL - What are the meanings of the hardware compression/decompression driver error codes
HiFN error codes
Hifn error codes
| Explanation
|
-1 unsuccessful return code
| This can be a true hardware failure and cards may need to be replaced. However, sometimes the driver will recover on it's own with a reboot of the HiFN driver processors (to reboot processors need to reboot VTL server). if processors all reboot cleanly (see doc id 1187199.1 for troubleshooting steps), then it was an erroneous error and no further action is required.
|
-2 H9630vtl_buffer_size
| Buffer size exceeded
|
|---|
-3 buffer too small for results
| This is generated when the compressed data will not fit into the output buffer. Driver returns a -3 and then the data is writen to the disk uncompressed.
This is an informational only message.
Note: A rc=-3 should not occur on a decompress, as whatever was previously compressed fit on the output buffer and the same buffers are used to decompress. If this occurs escalate to VTL engineering for analysis.
|
-4 invalid request or argument
| The HiFN driver was given an invalid request or argument.
Action will be retried
|
-5 command ring full
| Temporary error...
|
-6 failure detected but can continue
|
Temporary HiFN Hardware compression/decompression failure. Backup operation needs to be resubmitted.
