How reproducible:

Steps to Reproduce:
1.No symolic link exits for hotplugs

What sort of symbolic links are you looking for?

What architecture (you mentioned 'alpha', that doesn't seem right. :) )
Comment 3 Kunal Alva 2004-09-06 07:33:56 EDT
Usually for hotplugging support a symbolic link is being created 
which exactly refers to the specific device number of a (e.g.) DASD. 
It means that like in UDEV or DEVFS I have the opportunity to refer 
to a DASD for instance as /udev/dasd/0.0.<devno>/part1. This entry 
infact would be a symbolic link to the original DASD name which might 
be for instance /dev/dasdX1.

My apologies the defect I raised is for Red Hat Enterprise Linux Beta 
Since I do not have the access rights yet, for Red Hat Enterprise 
Linux Beta , I have raised under Red Hat Enterprise Linux.

I have made the following observations.
When I added two more entries for DASD in the file /etc/udev/rules.d/50-
KERNEL="dasd*[a-z]", SYMLINK="dasd/%b/disc"
KERNEL="dasd*[0-9]", SYMLINK="dasd/%b/part%n"
The sym links are getting created in the directory /dev/dasd.
However I feel for zSeries these entries should present by default.Please let 
me know your concern on this.
Comment 9 Harald Hoyer 2004-11-19 09:32:10 EST
are these the only rules you need for udev??

Yes these are the only two entries , which I added to create symbolic links 
for dasd. It works .
