I'm curious about the behavior where any udev labeled device causes that corresponding listing to disappear from fdisk, sfdisk, or in the case of RDAC, lsvdev.
I have seen this on both EMC clariion and Sun Storagetek/Engenio 6540 arrays.
We use RHEL5.1 and udev to create persistent labels for... (2 Replies)

upstart-udev-bridge
upstart-udev-bridge(8) System Manager's Manual upstart-udev-bridge(8) NAME
upstart-udev-bridge - Bridge between Upstart and udev SYNOPSIS
upstart-udev-bridge [OPTIONS]... DESCRIPTION
upstart-udev-bridge receives information about kernel uevents that udev(8) has completed and creates init(8) events for them. It emits events which match the pattern "S-device-A" where 'S' is the udev subsystem and 'A' is one of added, changed or removed, which correspond to the past tense of the udev 'action'. See udev(7) and for further details. Assuming /sys is mounted, possible values for subsystem for your system are viewable via /sys/class/. OPTIONS
--daemon Detach and run in the background. --debug Enable debugging output. --help Show brief usage summary. --no-strip Do not modify udev message contents. By default, all udev data will have non-printable bytes removed. This option reverts the behav- iour to not modifying the data in any way. This option is not recommended since specifying it could result in udev(7) events not being emitted as Upstart events should any of your hardware expose non-printable characters to the kernel. You can establish whether this is happening by running without specifying this option but with the --debug option. --verbose Enable verbose output. EXAMPLES
Some examples of Upstart events generated by this bridge: net-device-added Event emitted when a network device is added. net-device-removed Event emitted when a network device is removed. graphics-card-added Event emitted when a graphics device is available to the system. NOTES
This is a temporary tool until init(8) itself gains the functionality to read them directly; you should not rely on its behaviour. AUTHOR
