2 In the Dell PowerEdge SC1435 servers delivered July 2008,
3 there are several BIOS settings that need to be frobbed on setup.
5 in the setup screen at F2:
6 - CPU -> Virtualization Technology: on
7 - Boot Sequence: disable NIC
8 - Integrated Devices -> Embedded Gb NIC: turn off PXE
9 - Serial Communication:
10 - Serial Communication: On with Console Redirection via COM2
11 - External Serial Connector: COM1
12 - Failsafe Baud Rate: 57600
13 - Remote Terminal Type: VT100/VT220
14 - Redirection After Boot: Disabled
17 - Advanced -> "Wait for 'F1' If Error" -> Disabled
18 - Advanced -> Power Button Function -> 4 Seconds Override
19 - Advanced -> PCIe/PnP -> Load Onboard LAN N Option Rom -> Disabled
20 - Advanced -> Serial Port -> SOL -> Redirection After BIOS Post -> BootLoader
21 - Advanced -> Serial Port -> COM -> Console Redirection -> Enabled
22 - Advanced -> Serial Port -> COM -> Redirection After BIOS Post -> BootLoader
23 - Advanced -> PCIe -> Disable all OPROMS
24 - IPMI -> BMC Network Configuration
25 - Boot order: USB Hard Disk, Removable, Hard Disk, UEFI Shell
28 - 1000M for /boot in raid1 of sda1, sdb1
29 - rest for LVM in raid1 of sda2, sdb2
32 - install a vanilla kernel, not xen;
33 will install xen hypervisor from backports in our later custom install
35 in the setup screen for remote management, at Ctrl-E:
36 - Turn on IPMI over LAN
37 - IP is (main IP) =~ s/18.181.0/10.5.128/
38 e.g. 10.5.128.221 for citadel-station == 18.181.0.221
39 - netmask is 255.255.0.0
40 - Set the password to the XVM root
42 All of these settings are reflected on all 8 servers in the production
45 In the debian installer:
46 - 500M for /boot in raid1 of sda1, sdb1
47 - rest for LVM in raid1 of sda2, sdb2
50 - install a vanilla kernel, not xen;
51 will install xen hypervisor from backports in our later custom install.
54 Currently allocated backend IPs:
63 10.5.128.23 m-a (not installed)
65 10.5.128.128 RAID group portal
66 10.5.128.129 RAID device/management
73 10.5.128.226 g-d IPMI (currently unplugged)
75 10.5.128.228 m-a IPMI (not configured)
76 18.4.58.231 new c-s IPMI
77 18.4.58.232 new a-s IPMI
78 18.4.58.233 new s-m IPMI
79 18.4.58.234 new a-m IPMI
80 18.4.58.235 new d-o IPMI
81 18.4.58.236 new g-d IPMI
82 18.4.58.237 new b-f IPMI
83 18.4.58.238 new m-a IPMI
93 10.6.128.23 m-a (not installed)
95 10.6.128.129 RAID device/management
97 10.6.128.229 g-d IPMI (temporary hardware)
102 Copy /etc/invirt/conf.d/iscsi from another prod host before trying to
103 start iscsi (possibly before installing xvm-host)
105 After installing xen:
106 /etc/default/grub (note the commenting out!):
108 #GRUB_HIDDEN_TIMEOUT=0
109 #GRUB_HIDDEN_TIMEOUT_QUIET=true
111 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
112 GRUB_CMDLINE_LINUX="console=hvc0 earlyprintk=xen nosplash"
113 GRUB_CMDLINE_XEN="loglvl=all guest_loglvl=all com2=115200,8n1 console=com2,vga"
114 GRUB_DISABLE_OS_PROBER="true"
118 ln -s /usr/share/qemu-linaro /usr/share/qemu
120 Change /etc/hostname to the host's FQDN
122 /etc/sysctl.conf (yes, you need all three):
123 net.ipv4.conf.eth0.rp_filter = 0
124 net.ipv4.conf.eth1.rp_filter = 0
125 net.ipv4.conf.all.rp_filter = 0
127 Comment out in /etc/init.d/clvm:
128 # if [ ! -f /etc/cluster/cluster.conf ]; then
129 # log_failure_msg "clvmd: cluster not configured. Aborting."
133 # if ! cman_tool status >/dev/null 2>&1; then
134 # log_failure_msg "clvmd: cluster is not running. Aborting."
139 On boot, you'll need to run /usr/lib/xvm-iscsi-connect to bring up
140 iscsi. Multipath will come up automatically along with that.
142 Make sure corosync is running before starting clvmd (I know, obvious, but still)
144 Copy /etc/init/ttyhvc0.conf from another new host
146 On another XVM host, run ipmitool -I lanplus -U ADMIN -H <address of
147 new machine's ipmi> shell
149 user set password <ID of ADMIN user>
150 Change the password to the XVM root password
153 Serial console: from another XVM host run ipmitool -I lanplus -U ADMIN
154 -H <address of new machine's ipmi> shell
157 To bring up the iSCSI backend, you'll need to ping:
158 ping 18.4.{58,59}.{128,129}
