 Advisory Information

RELEASE DATE: 06 October 2003


This EA is being updated to provide a pointer to a replacement ERP for the one announced in the original EA.

TThe replacement ERP contains fixes for the following three AdvFS-related issues:

  • HP Tru64 UNIX - Errors with V5.1A Patch Kit 5, described in this EAbr>  
  • HP Tru64 UNIX 5.1A PK5 Possible Memory Corruption (BU030718_EW01)
  • HHP Tru64 UNIX V5.1A PK5 Mandatory Patch for Potential Unexpected AdvFS Domain Behavior (BU031001_EW01)

Special Installation Instructions/span>

AAfter installing the ERP, users should run fixfdmn on domains that may have become 90% full at any time after PK5 was installed.

The original EA, with the replacement 5.1A PK5 location, follows./span>


TThe Early Release Patch (ERP) Kit delivered in this Engineering Advisory (EA) corrects the following AdvFS issue identified in the HP Tru64 UNIX operating system:

After installing Tru64 UNIX V5.1A PK5(BL23), errors may be received when executing multiple threads (tar/cp/vrestore/cat) simultaneously on an AdvFS domain with very large files (typically tens of gigabytes) while under heavy I/O load. These errors can appear as any of the following.

  • I/O errors
  • kernel memory faults when trying to access a subXtntMap which is null
  • ENO_MORE_MEMORY errors/span>


This behavior is limited to Tru64 UNIX V5.1A Patch Kit 5 (BL23).



UUntil the HP Tru64 UNIX corrections are available in the mainstream release patch kits, HP is releasing the following ERP kit publicly for use by any customer. The ERP kits use dupatch to install and will not install over any Customer Specific Patches (CSPs) that have file intersections with the ERP. Contact your service provider for assistance if the installation of the ERP is blocked by any of your installed CSPs.

The fix contained in the ERP kit for this problem is scheduled to be available in the following mainstream patch kit:

  • HP Tru64 UNIX V5.1A PK6 (BL24)
