Solution Type Problem Resolution Sure Solution 1131534.1 : VTL - Receiving "decompression failed -6" errors with HiFN hardware compression card
In this Document
Applies to:Sun StorageTek VTL Plus Storage Appliance - Version: 2.0 - Build 1590d to 2.0 - Build 1656 - Release: 2.0 to 2.0Oracle Solaris on SPARC (64-bit) . ***Checked for relevance on 14-07-2011*** (dd-mm-yyyy) SymptomsReceiving decompression failed -6 errors with hardware compression card. Receiving Hardware Compression Card Failed Receiving Temporary Hifn HW Decompression failure ChangesN/ACausen many cases (not all) the VTL Console will show a compression HW failure, but was not an actual failure. It's a temporary processor reset if ActualSize and RetSize are equal and no further action required.Another form of the -6 errors is an actual error and the ActualSize and RetSize are not equal. These are true decompression errors (many causes) and need to be escalated to VTL Support. See details in solution section below. SolutionTo determine whether the -6 errors are temporary or true failures: Open VTL server messages file and grep for "h9630": 1. If temporary errors are found: "Temporary Hifn HW Decompression failure, return code = -6 " then decompression operation will be retried and in most cases succeed. Example messages:Feb 7 19:45:21 xxxxxxxx h9630vtl_drv: [ID 457317 kern.warning] 2. If error message shows that "ActualSize" and RetSize" are equal: "Decompression failed -6, CompSize 254504, ActualSize 262144, RetSize 262144" then these are temporary errors and operation should be redriven by backup app. Example messages:Feb 7 19:45:21 xxxxxxxx genunix: [ID 459543 kern.notice] 3. If error message shows that "ActualSize" and RetSize" are NOT equal: "Decompression failed -6, CompSize 250709, ActualSize 262144, RetSize 163" then these are true decompression failures and case should be escalated to Oracle VTL Support.
