From robert.clift at navy.mil Thu Dec 20 19:52:19 2012 From: robert.clift at navy.mil (Clift, Tom CIV NSWCDD, K55) Date: Thu, 20 Dec 2012 14:52:19 -0500 Subject: Oracle X2-4 not showing all drives Message-ID: <4496D03A-7D32-4E89-83A4-8D7C5D0E8276@mimectl> All, I am in the process of building two Redhat Servers on Oracle X2-4 hardware. Redhat version is 5.7. Both systems have two scsi hard drives, however I can only see one drive. Is there a command similiar to "format" from the Solaris world that will list out all available disk drives? If I use fdisk -l, I only see sda1 and sda2 which is the drive that Redhat was installed to. I don't see anything listed in /dev similiar to sdb or hdb which is the way I understand it to work. I am in the process of learning Redhat after a long background with Solaris. -------------- next part -------------- An HTML attachment was scrubbed...

The reason I ask that is because this hardware platform is generally known as a virtualization platform. But it sounds like you are seeing a single 'logical' drive. This server-class hardware should have a raid/drive controller presenting the logical disk to the OS. I would check your POST for options to configure a Raid/Disk controller. It might be defaulting to a mirrored set; which would only present the OS with a single logical drive. That is the first thing I would check at least. Also, why aren't you installing on RHEL6?

I am looking into that now but but here is some information on the Redhat install. The system has two(2) 300GB scsi hard drives. Looks like the default RedHat install builds Physical Volume on /dev/sda2 of size 298GB. Then a Volume Group is created on the PV. Then two Logical Volumes are created on the VG and they are sized 143GB and 137GB. Root is then install on LogVol00 and swap on LogVol01. A 100MB /boot partition is created on /dev/sda1. PV=/dev/sda2(298GB) ---> VG=PV ---> LV=2 Logical Volumes(140GB each) ---> "/" on LogVol00 and "swap" on LogVol01 If you are just seeing this for the first time, my problem is not being able to see the other disk drive in the system from the RedHat OS. I do see the drive at boot time during the hardware devices discovery. Thanks in advance, -------------- next part -------------- An HTML attachment was scrubbed... URL:
