UCS B-series blades and RHEL 6.x installation over PXE - virtual media problem

abrindeyev

We're trying to install RHEL 6.1 on B-200 M1 blade server and facing following issue: Anacoda see two virtual devices from UCS as /dev/sda and /dev/sdb. Two physical disks are referred as /dev/sdc and /dev/sdd.

Can we remove all virtual media devices or move them on PCI bus to avoid that problem?

Next blade in the same chassis does not have that problem - physical disks are named /dev/sda and /dev/sdb as expected.

Andrey,

I installed 64 bit RHEL 6.1 on B 200 M1 server and do not observe this behavior.

Blade has a LSI raid controller with RAID 0 configured on two local HDDs.The RAID array is listed as sda

# fdisk -l /dev/sda

Disk /dev/sda: 146.0 GB, 145999527936 bytes

   Device Boot      Start         End      Blocks   Id  System

/dev/sda1   *           2         501      512000   83  Linux

/dev/sda2             502      139236   142064640   8e  Linux LVM

#  uname -a

Linux RHELv61-server 2.6.32-131.0.15.el6.x86_64 #1 SMP Tue May 10 15:42:40 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux

# cat /etc/redhat-release

Red Hat Enterprise Linux Server release 6.1 (Santiago)

I did a installation using virtual CD via KVM.

At what stage of installation and where do you observe these virtual devices ?
