HP-UX 11i v3 Persistent DSF Migration Guide

Planning Worksheets
This section lists sample worksheets (in table format) to identify, collect, document, and migrate legacy DSFs
and hardware paths. If users have applications referencing legacy hardware paths, these paths need to be
migrated as well. The lists document what needs to be changed and provide a record to recover from in case
there are any problems with the migration.
These records are for illustration purposes only and the DSFs, hardware paths and file names listed are
examples. Users would most likely save electronic copies of ioscan and other command output as well (per
the migration steps above).
1. Mapping legacy to persistent DSF. The following table is derived from the output of ioscan –m dsf.
This table is needed if there are any applications referencing legacy DSFs.
Persistent DSF Legacy DSF(s).
/dev/rdisk/disk14 /dev/rdsk/c7t0d0
/dev/rdsk/c4t0d0
2. Mapping legacy hardware path to lunpath hardware path. The following table is derived from the
output of ioscan –m hwpath. This table is only needed if there are any applications referencing
legacy hardware paths.
LUN Hardware path Lunpath Hardware path Legacy hardware path
64000/0xfa00/0x6 0/1/1/0.0x0.0x0 0/1/1/0.0.0
