Configure HP ILO via ESXi CLI – Reset ILO Password via ESXi CLI

December 13, 2012 ~ admin

The HP server must have been installed with the HP ESXi ISO -or- Updated via VMware Update Manager (VUM) with the latest vibs from vibsdepot.hp.com.

The process to configure the ILO is as follows:

1. SSH to the ESXi host

2. cd /opt/hp/tools

3. Export the current config: ./hponcfg -w /tmp/ilo_config.txt

4. Edit the above export config file (/tmp/ilo_config.txt) and change the following variables:

<IP_ADDRESS VALUE = “10.10.10.20”/>
<SUBNET_MASK VALUE = “255.255.255.0”/>
<GATEWAY_IP_ADDRESS VALUE = “10.10.10.1”/>
<DHCP_ENABLE VALUE = “N”/>

5. Flash the updated config to the ILO: ./hponcfg -f /tmp/ilo_config.txt

[Let the ILO restart]

6. You must now reset the Administrator password. Create the file: reset_admin_pw.xml with the below info and add the new password in the password section:

<ribcl VERSION="2.0"> <login USER_LOGIN="Administrator" PASSWORD="YOUR-NEW-PASSWORD"> <user_INFO MODE="write"> <mod_USER USER_LOGIN="Administrator"> <password value="newpass"/> </mod_USER> </user_INFO> </login> </ribcl>

7. Flash “reset_admin_pw.xml” to the ILO: ./hponcfg -f reset_admin_pw.xml

8. Done. You should be able to reach the ILO web management interface and login as Administrator.

Reset TopSpin Infiniband Switch Password

November 22, 2012March 24, 2015 ~ admin

To reset the password on a TopSpin Inifiband switch you’ll need to boot the system in the single user mode.

To do this:

Connect a console to the serial port and stop the booting at ppcboot. Do the following:

1) at the “Hit any key to stop autoboot:” prompt, press a key quickly ( <5sec )

2) type in (without quotes, press enter): “setenv bootargs $(bootargs) -s”

3) type in (without quotes, press enter): “bootd”

4) you are now running linux in single user mode – on the recovery area readonly filesystem; load the Disk On Chip driver, type in (without quotes, press enter): “/sbin/insmod /sbin/doc.o”

5) mount the /topspin Disk On Chip filesystem, found on /dev/msys/fla2, on an available directory (such as /tmp), type in (without quotes, press enter): “mount -t ext3 /dev/msys/fla2 /tmp”

6) the actual config file, config:startup-config, will now be accessible at the path /tmp/config/runtime/startup-config – either remove this file (if there is no other config data to worry about), or vi the file to remove the password spec for user “super” – remove the line with syntax similar to “username super password {integer} {encrypted password}”, sync and reboot; the super user password will revert to the default value “super”.

See below for an example:

VMware converter does not find or recognize LVM CentOS 6 |-wi-ao|

October 12, 2012November 20, 2012 ~ admin

As discussed in this VMware thread: http://communities.vmware.com/thread/413602

VMware converter 5 fails to recognize LVM slices on CentOS 6 or Red Hat 6.

Log files shows:

WARN storage.lvm ]: Failed to match lvs output line ‘ lv_root|vg00|587034787840B|-wi-ao–|1

This issue is: -wi-ao– converter is expecting: -wi-ao (no –)

Two fixes:

1. downgrade to: lvm2-2.02.72

-or-

2. Wrap lvm with:

/sbin/lvm.wrapper $@ | sed -e ‘s/-wi-ao–/-wi-ao/’

VMware “Unable to connect to the MKS:”

January 24, 2012March 24, 2015 ~ admin

Unable to connect to the MKS: Login (username / password) incorrect

Open /etc/vmware/config with a text editor.
Add this: vmauthd.server.alwaysProxy = “TRUE”

Check your firewall config/network setup. This error is caused by your vSphere client not able to communicate with the ESX/ESXi host directly.

All “Unable to connect to the MKS:” errors are network issues. Do not be fooled by the mention of certificate issues…

Connect vCenter To ESX/ESXi Through MIP NATd IP

November 22, 2011October 13, 2012 ~ admin

To make both connectivity to vCenter and clone operations function with NATd ESX service consoles:

1. In Vmware vCenter client, disable Vmware HA and DRS.
2. In Vmware vCenter client, disconnect the host. The VMs will continue to run.
3. Log in to the ESX service console via SSH and change to root.
$ ssh
$ sudo su –

1. Change the IP address in /etc/hosts to the public IP.
$ vi /etc/hosts
$ cat /etc/hosts
127.0.0.1 localhost
::1 localhost
33.33.22.22 esxhost.example.com esxhost

1. Verify the hostIP address is the public IP, and add preserveServerIp in /etc/opt/vmware/vpxa/vpxa.cfg .
$ vi /etc/opt/vmware/vpxa/vpxa.cfg

…
33.33.22.22
…

true

1. Restart the VPXA service.
$ service vmware-vpxa restart

1. Log out of the ESX service console.
2. In Vmware vCenter client, reconnect the host. You may need to re-enter the root user�s credentials.
3. In Vmware vCenter client, enable Vmware HA and DRS.

SSH Client in ESXi

November 3, 2011March 15, 2012 ~ admin

By default, the �ssh� command does not exist in VMware ESXi 4.1.

To create it, login as root and execute the following command:

ln -s /sbin/dropbearmulti /bin/ssh
