Description Andrew Gaffney (RETIRED) gentoo-dev 2007-11-06 21:17:25 UTC
I was testing a 2007.1 x86 minimal CD I built in vmware, and I noticed it was behaving a bit oddly. It was scanning every ID on the virtual buslogic scsi controller and assigning a dev node, even though it didn't detect a drive. It had up to /dev/sdo assigned by the time it finished scanning.

This *is* an upstream issue, as the Ubuntu livecd gets up to /dev/sddi (it scans all LUNs on each ID) before I killed it.

I'm attaching the dmesg from the minimal CD. Also, here's a list of the dev nodes that were created:

livecd ~ # ls -l /dev/sd?                                                      
brw-rw---- 1 root disk 8,   0 Nov  6 16:01 /dev/sda

Whoops, wrong file.
Comment 3 Mike Pagano gentoo-dev 2008-02-23 21:32:40 UTC
Is this still an issue? Has any testing begun with a 2008.0 x86 minimal CD built in vmware, yet?
Comment 4 Andrew Gaffney (RETIRED) gentoo-dev 2008-02-23 23:03:53 UTC
This is still an issue with 2.6.23-gentoo-r8 in app-emulation/vmware-server-1.0.4.56528
Comment 5 Daniel Drake (RETIRED) gentoo-dev 2008-03-16 21:09:17 UTC
Smells like a vmware bug -- apparently this is a regression in 1.0.4 over 1.0.3

There's no evidence to suggest that this is a linux driver bug, but I sent a mail upstream anyway:
http://marc.info/?l=linux-scsi&m=120570006318199&w=2

I'd suggest you contact vmware about this problem too.

Can't do much more than that, sorry. The vmware forums suggest that changing to the LSI driver will solve the problem.
