Hi Rich
Thanks very much for making us all aware of this.
Questions, if I may:
- if a RHEL 5.6 system is upgraded to 5.7, do existing persistent names get
changed to the 'user-friendly' persistent names? If so, this would 'break' an
existing NetWorker configuration, requiring some re-configuration.
- do I assume correctly that NetWorker for Linux will be able to use these
new-format persistent names?
- is there a way to instruct udev to NOT use these new 'user-friendly' names in
an upgrade situation (which would preserve the existing names, and so would NOT
'break' an existing NetWorker configuration)?
Thanks

Subject: [Networker] Changed persistent device names in RHEL 5.7
Heads up for anyone else using persistent device names on RHEL:
RHEL 5.7 (kernel 2.6.18-274.el5, udev-095-14.27.el5) adds "user-friendly"
descriptions to /dev/tape/by-id/*, thus breaking anything that depends on
persistent names. /dev/tape/by-id/scsi-1IBM_3573-TL_XXXXXXXXXXXX_LL0 becomes
/dev/tape/bu-id/scsi-1IBM_3573-TL_XXXXXXXXXXXX_LL0-changer, and the drives
themselves get -sg, -st, -nst suffixes.
This is quite easy to fix, but takes some troubleshooting time if you weren't
expecting it.
