How to setup virtual iLO Remote Console

September 14th, 2011 No comments

In the new release of HP Integrity Virtual Machines 4.30, HP added a new feature which allows you to access the guest console by logging into a specific IP address. This feature is called virtual iLO Remote Console and should be configured with hpvmmodify.

Looking at the guest status (hpvmstatus -p) the following is observed:
[Remote Console]
Remote Console not configured

This is how to configure the IP address of the virtual iLO Remote Console:
root@vmhost1:/# hpvmmodify -p 1 -K 192.168.11.193 -L 255.255.255.0

What the command does is configuring IP alias as could be seen in netstat:
lan0:110  1500 192.168.11.0    192.168.11.193  0                  0     0                  0     0

Running again hpvmstatus we see that the Remote Console is now configured:
[Remote Console]
Remote Console Ip Address:      192.168.11.193
Remote Console Net Mask:        255.255.255.0

Now about the users, by default the root user of the host is able login to all virtual consoles, although it’s not listed in following section:
[Authorized Administrators]
Oper Groups             :
Admin Groups            :
Oper Users              :
Admin Users             :

Let’s create a dedicated user for the first guest and then login:
root@vmhost1:/root# useradd -d /var/opt/hpvm/guests/vm01 -c ‘vm01 console’ adminvm1
root@vmhost1:/root# passwd adminvm1
root@vmhost1:/root# hpvmmodify -p 1 -u adminvm1:admin

Running status again we can see that the user is added to the administrators:
[Authorized Administrators]
Oper Groups             :
Admin Groups            :
Oper Users              :
Admin Users             : adminvm1

Let’s try now to login with our newly created user:
sve@angmar:~$ ssh adminvm1@192.168.11.193
Password:

vMP MAIN MENU

CO: Console
CM: Command Menu
CL: Console Log
SL: Show Event Logs
VM: Virtual Machine Menu
HE: Main Help Menu
X: Exit Connection

[vm01] vMP>

Voila, it’s working!

 

To enable access to the virtual iLO Remote Console through telnet (which by default is not supported) these two patches has to be applied on the host: PHCO_41595 and PHNE_41452. Two more considerations should be taken into consideration: The virtual iLO Remote Console’s SSH server host keys can change as it uses the host system’s SSH server host keys. If the guest is migrated to another system then these host keys will change. Another one is that guest administrator accounts are not migrated during Online VM Migration.

How to mount an ISO image under HP-UX 11iv3

September 12th, 2011 No comments

So what do I do if I want to mount an iso image under HP-UX.

Previously I had to create a logical volume, copy the content of the ISO on in and then mount the logical volume, like this one:

root@vmhost1:/# ll /tmp/test.iso
-rw-r--r--   1 root       sys        105906176 Sep  8 11:57 /tmp/test.iso
root@vmhost1:/# lvcreate -L 102 -n lvtest vg00
Warning: rounding up logical volume size to extent boundary at size "128" MB.
Logical volume "/dev/vg00/lvtest" has been successfully created with
character device "/dev/vg00/rlvtest".
Logical volume "/dev/vg00/lvtest" has been successfully extended.
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf
root@vmhost1:/# dd if=/tmp/test.iso of=/dev/vg00/rlvtest bs=1024k
101+0 records in
101+0 records out
root@vmhost1:/# mount /dev/vg00/lvtest /mnt
root@vmhost1:/# bdf /mnt
/dev/vg00/lvtest    102888  102888       0  100% /mnt

 

With the enhancement of ISOIMAGE-ENH, now you’re able to mount and umount iso images (like in Linux):

root@vmhost1:/# kcmodule fspd=loaded
root@vmhost1:/# mount -F cdfs /tmp/test.iso /mnt
root@vmhost1:/# bdf /mnt
/dev/fspd1          102888  102888       0  100% /mnt

 

If you get an error like this one:
mount: /tmp/test.iso is an invalid operand
then most probably you’ve forgotten to load the fspd module.

The package could be installed during installation or downloaded from Software Depot home, here and it’s available only for HP-UX 11iv3.

Oracle to stop writing software for Itanium processor

March 23rd, 2011 No comments

Few months after Oracle have changed the cpu core factor for the new Itanium series 93XX from 0.5 to 1, they now said that decided to discontinue all software development on the Intel Itanium chips. This is almost an year after Microsoft announced that Windows Server 2008 R2 will be the last version of Windows server to support Itanium chips. Red Hat also dropped the Itanium support in 2009 and the last supported version was RHEL 5.6. Until now HP and IBM were the two major competing companies in the Enterprise Mission Critical servers, HP with Superdome with dual core Itaniums chips and now Superdome2 with quad-core Itanium chips, IBM are having their p795 with 4/8 cores. I worked with HP-UX for six years now and I really liked the Itanium, but IBM chips are way more powerful and already had 8 cores per chips and they used to have the same cpu core factor with Itanium. Probably the today’s announcement heralds an end of an era.

You can read Oracle Press release here, they also released a support table of product versions which will be the last supported on Itanium chips. As a result Intel reaffirms their commitment to the development of the Itanium chip, read it from the Intel’s newsroom.
