 Advisory Information
 

RELEASE DATE: 2006-06-09

DESCRIPTION
This patch fixes problems fixfdmn has with AdvFS domains with multi-page RBMT files, multiple SBM extents, more than one root tag file, clone filesets, or when given an invalid fileset argument.

The following is a list of the problems fixed:

Fixfdmn does not properly handle domains with multi-page RBMT files. Error messages are of the type:

fixfdmn: Gathering volume information
fixfdmn: Opening directory '/etc/fdmns/hsv1a-fs01'.
fixfdmn: Opening the volumes.
fixfdmn: Setting volume '/dev/disk/dsk1101a' to volume number 1.
fixfdmn: Checking the RBMT.
fixfdmn: Found corruptions in next RBMT page mcell.
fixfdmn: Found the transaction log onvolume /dev/disk/dsk1101a.
fixfdmn: Mcell (1,0,0) is corrupt.
fixfdmn: Mcell (1,0,4) is corrupt.
fixfdmn: Loading subsystem extents.
fixfdmn: Can't convert page 12 to an LBN,valid range is 0 to 12.
fixfdmn: Can't convert [R]BMT page 12 to LBN.
fixfdmn: Error collecting subsystem extents.

When growing an AdvFS volume, if there are multiple extents representing an SBM, fixfdmn does not work on all the SBM extents. Example error messages follow:

fixfdmn: XOR value for SBM Page 6 is not correct.
fixfdmn: Checking the RBMT.
fixfdmn: XOR value for SBM Page 6 is not correct.
fixfdmn: XOR value for SBM Page 7 is not correct.
fixfdmn: XOR value for SBM Page 107334860 is not correct.
fixfdmn: Unable to find the starting block of the SBM.

Fixfdmn fails when a clone's original fileset is missing a tag which is present in the clone fileset.

Running fixfdmn only on a clone fileset always fails with an error. Example error messages follow:

fixfdmn: Checking the RBMT.
fixfdmn: Clearing the log on volume /dev/disk/dsk5c.
fixfdmn: Checking the BMT mcell data.
fixfdmn: Checking the deferred delete list.
fixfdmn: Checking the root tag file.
fixfdmn: Checking the tag file(s).
fixfdmn: Checking the mcell nodes.
fixfdmn: Checking the BMT chains.
fixfdmn: Error correcting the BMT chains on fileset clone.
fixfdmn is not able to continue, no changes made to domain, exiting

Fixfdmn exits when it encounters a domain with more than one root tag file. An example error message follows:

fixfdmn: Unable to continue, more than one root tag file.

Fixfdmn does not properly handle domains with multi-page RBMT files that have their last page full and need to grow. Domains of this type will domain panic when being activated (mounting the first fileset). An example error message follows:

WARNING: file tag -6 in fileset "" has > 64K extent mcells.

 

SCOPE

The following versions are affected:

  • HP Tru64 UNIX V5.1B-3
  • HP Tru64 UNIX V5.1B-2/PK4
  • HP Tru64 UNIX V5.1A PK6
 
RESOLUTION

HP is releasing the following ERP kits publicly for use by any customer. The kits use dupatch to install and will not install over any Customer Specific Patches (CSPs) that have file intersections with the ERP.

The fixes contained in the ERP kit are  available in the following mainstream patch kit:

HP Tru64 UNIX Version 5.1B-4

The kit distributes the following file:
