hpacucli Error: No controllers detected

I have a HP Proliant server that is using hardware RAID for the boot disk but when I used hpacucli no status was shown

root@linux:~ # hpacucli ctrl all show config

Error: No controllers detected.

Verified if I have RAID and the server model

root@linux:~ # lspci | grep -i raid

root@linux:~ # dmidecode | grep -i proliant
Product Name: ProLiant DL380p Gen8
Family: ProLiant

I had hpacucli 8.70 and I read that old versions that causes problems like this. So I uninstalled

root@linux:~ # rpm -qa | grep hpacucli

root@linux:~ # rpm -e hpacucli

And installed the newest version

root@linux:~ # rpm -ivh /tmp/hpacucli-9.40-12.0.x86_64.rpm

DOWNGRADE NOTE: To downgrade this application to any version prior to 9.10.x.x, the current RPM must be manually uninstalled using the “rpm -e” command before any prior versions can be installed.

LOCKING NOTE: The locking mechanism starting with versions 9.10.X.X, are not compatible with prior versions of the applications. Therefore, mixing older and newer versions of the various applications (ACU, HPACUCLI, HPACUSCRIPTING) is not recommended.

After this, the utility was showing my drives

Suse Linux 11 stuck at boot: Set System Time to the current Hardware Clock

I was having a problem with a SLES 11 running under VMware where it stuck at boot.
Set System Time to the current Hardware Clock
To solve this problem I booted in single user mode and moved the script that sets the time

root@linux:~ # mv /etc/init.d/boot.clock /root

pvmove: Insufficient free space with both disks the same size

I was migrating some LUNs to another storage.

After creating the LUNs with the same size, I intended to move the data to the new disk but I was getting there was insufficient free space

root@linux:~ # pvmove /dev/mapper/bkpcvrdd01 /dev/mapper/bkpcvrdd01newp1
Insufficient free space: 12800 extents needed, but only 12799 available
Unable to allocate mirror extents for pvmove0.
Failed to convert pvmove LV to mirrored

What happens is that the source disk is bigger than the new disk.

root@linux:~ # pvdisplay /dev/mapper/bkpcvrdd01 /dev/mapper/bkpcvrdd01newp1
— Physical volume —
PV Name /dev/mapper/bkpcvrdd01
VG Name bkpcvrdvg
PV Size 50.00 GB / not usable 640.00 KB
Allocatable yes (but full)
PE Size (KByte) 4096
Total PE 12800
Free PE 0
Allocated PE 12800
PV UUID giRfdd-oDKH-12W7-ObwE-nFoN-nF0L-3OFlK5

— Physical volume —
PV Name /dev/mapper/bkpcvrdd01newp1
VG Name bkpcvrdvg
PV Size 50.00 GB / not usable 3.31 MB
Allocatable yes
PE Size (KByte) 4096
Total PE 12799
Free PE 12799
Allocated PE 0
PV UUID MXxLNF-hDbU-eaEp-0wyW-ly1l-N1FJ-Bh2fNk

Both are the same size but due to the physical structure, each disk shows a different size.

Run fdisk -l and observe the size. This is the disk after a LUN expansion.

root@linux:~ # fdisk -l /dev/mapper/bkpcvrdd01new

Disk /dev/mapper/bkpcvrdd01new: 54.2 GB, 54223962112 bytes
255 heads, 63 sectors/track, 6592 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/mapper/bkpcvrdd01newp1 1 6592 52950208+ 8e Linux LVM

Now compare both disk sizes:

53.6 GB, 53687746560 bytes
53.6 GB, 53686370304 bytes

Remove virbr0 interface in Linux

virbr0 is an ethernet bridge

root@linux:~ # ifconfig virbr0
virbr0 Link encap:Ethernet HWaddr 00:00:00:00:00:00
inet addr: Bcast: Mask:
inet6 addr: fe80::200:ff:fe00:0/64 Scope:Link
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:41 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 b) TX bytes:7630 (7.4 KiB)

You use brctl to manage the interface.
brctl is used to set up, maintain, and inspect the ethernet bridge configuration in the linux kernel

root@linux:~ # brctl show
bridge name bridge id STP enabled interfaces
virbr0 8000.000000000000 yes

Verify if libvirtd is running

root@linux:~ # service libvirtd status
libvirtd (pid 12529) is running…

Verify if there is any host running. In my case there isn’t

root@linux:~ # virsh list
Id Name State

This is the default network set-up for the virtual machines

root@linux:~ # virsh net-list
Name State Autostart
default active yes

To remove first I’ll make sure the service libvirtd won’t be started automatically on next boot

root@linux:~ # chkconfig –list | grep -i lib
libvirt-guests 0:off 1:off 2:off 3:on 4:on 5:on 6:off
libvirtd 0:off 1:off 2:off 3:on 4:on 5:on 6:off

root@linux:~ # chkconfig libvirt-guests off
root@linux:~ # chkconfig libvirtd off

Destroy the network default

root@linux:~ # virsh net-destroy default
Network default destroyed

And undefine the network default

root@linux:~ # virsh net-undefine default
Network default has been undefined

Stop the libvirtd service

root@linux:~ # service libvirtd stop
Stopping libvirtd daemon: [ OK ]

The interface virbr0 is now gone

root@linux:~ # ifconfig virbr0
virbr0: error fetching interface information: Device not found


Mozilla Thunderbird showing error about disk space and there is disk space

Thunderbird complaining about disk space

Mozilla Thunderbird shows the error message: “There is not enough disk space to download new messages. Try deleting old mail, emptying the Trash folder, and compacting your mail folders, and then try again.”

You verify and there is plenty of disk space.

This is happening because Mozilla Thunderbird is a 32 bit application and your inbox folder has more than 2GB of email.

To solve your problem, create a new folder and then copy your email to it.
Delete your emails from the inbox and then run Compact Folders.
Close Mozilla Thunderbird and open it again. Your email should be downloading.

HP iLO 2 ClassNotFoundException com.hp.ilo2.remcons.remcons.class

You must have seen the dialog box with the error message when using the Remote Console applet that uses Java.

There is no definite solution. Use the Integrated Remote Console with Internet Explorer.

If you want to try some solutions:

First you verify if you are running the latest Java version. Some browsers refuse to load the applet if isn’t running the latest version.
Verify Java version

Check if the iLO 2 firmware isn’t too old. Upgrade to the latest version.
iLO 2 Firmware
Copy your configuration and then perform a factory reset to defaults in HP iLO 2 and then reconfigure it.

Nothing garantees that it will work but some people reported success with the steps shown above.
