unable to read partition table

Jump to solution

Setting up some new VI3.5 Dell 6950s. In the /var/log/messages log I keep seeing the below I/O Error. It's always preceeded by the vmware-hostd entry. I can't seem to track down what device it's talking about. Any ideas?

I disabled the virtual devices in drac and this mystical unidentifies lun disappeared. it seems to be related to the virtual floppy device.

isn't it one of those weird "virtual devices" all new servers seem to have these days?

I know it's not the DRAC's "Virtual Flash" device as that's a goofy 16MB partition. Already been there. I'm trying to think of order of initilization would help narrow it down. Is it true that Local SCSI should be first, then SAN, and then usb devices?

I just noticed the same issue for a Dell 2950 Server... hmmm , I will have a closer look.

I had the same problem with getting the following on my 2950 servers:

SCSI device sdg: 2097151 512-byte hdwr sectors (1074 MB)

sdg: I/O error: dev 08:60, sector 0

I/O error: dev 08:60, sector 0

unable to read partition table

now I disabled the virtual media option on the DRAC, the error seems to have gone (for now anway)

Many Thanks

AH! Just to verify with you. I have two Dell 2950s exhibiting bad behavior. Is the DRAC configurable from the bios? Did you have this behavior? http://communities.vmware.com/message/990868
