Listing the logical volumes inside the volume group. AIX can’t determine the LV type.
root@aix:/ # lsvg -l oravg
oravg:
LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT
oravg_lg ??? 1 1 1 closed/syncd N/A
ora_lv ??? 1064 1064 2 closed/syncd N/A
To solve this problem we’ll export then reimport the VG. But first we’ll need to deactivate it.
root@aix:/ # varyoffvg oravg
And we need at least one disk that is part of the volume group because it has the information needed to import.
root@aix:/ # lspv | grep oravg
hdisk251 00c5f1d097cc8a6e oravg
hdisk221 00c5f1d0a7bffede oravg
Now we run exportvg and the server will no longer know it once had the volume group.
root@aix:/ # exportvg oravg
Let’s list all the volume groups the server is aware that exists.
root@aix:/ # lsvg
rootvg
datavg
cache01vg
cache02vg
Only the rootvg is currently imported and active.
root@aix:/ # lsvg -o
rootvg
Let’s reimport the volume group. We need to declare one of the disks we listed before to reimport the volume group.
root@aix:/ # importvg -y oravg hdisk251
oravg
Next, we activate the volume group
root@aix:/ # varyonvg oravg
Listing the Volume Group. Volume Group TYPE listed.
root@aix:/ # lsvg -l oravg
oravg:
LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT
oravg_lg jfs2log 1 1 1 closed/syncd N/A
ora_lv jfs2 1064 1064 2 closed/syncd /u01

I had this weird error when trying to start an X11 application.
oracle@dbserver:~ $ xclock
xlib: connection to “localhost:12.0″ refused by server
Xlib: PuTTY X11 proxy: wrong authentication protocol attempted
Error: Can’t open display: localhost:12.0
Next you try the steps described here to transfer the authorization to the other account. But if you follow the steps and it simply doesnt work, check the filesystem where the home directory is.
oracle@dbserver:~ $ df -h .
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/rootvg-homelv
9.9G 9.4G 128K 100% /home
In this particular machine, I was having the authentication protocol error because the OS couldn’t update the .Xauthority file in the home directory.

Whenever you see a volume inside a disk group with the NEEDSYNC state, you simply run vxvol -g <disk group> resync <volume> to change the status back to ACTIVE.

I bought Street Fighter IV and when you start the game it asks for you to create or use an existing profile.
Any Game for Windows Live will enable you to create a profile that have all your games and you can show to other people what you have been playing. For example, see Microsoft Xbox Live Director of Programming Larry Hryb gamertag Major Nelson.
You enter your an email address and the password and it will download your profile to your computer but in my case it said “Can’t connect to Live – Error 0×80151911″
I read that the culprit was the MTU parameter set on your network. It can be set in any part of your network like your router or your Windows computer.
You need to set the MTU size to at least 1400 to make it download the profile. See your router documentation on how to change this parameter.
On a Windows computer you need to open regedit.exe and then search for the entries called MTU in HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Tcpip/Interfaces and select each interface (a random string of numbers). Right click the parameter MTU and choose decimal then type 1492 or 1500. Now you should be able to download your profile.

Summary:
Adapter at hardware path 0/2/1/0 : Fibre Channel driver has gone into
non-participating mode
Description of Error:
lbolt value: 3207
The Fibre Channel Driver has gone into non-participating mode
Frame Manager Status Register = 0×200002ff
Probable Cause / Recommended Action:
A cable or hardware problem exists. This can also be caused due
to the Tachyon TL adapter changing its AL_PA across a LIP.
Do the following:
1. Verify that the fiber optic cable is functional and securely
attached to the Fibre Channel Mass Storage Adapter.
2. After checking the cabling, execute a loopback test using
fcmsutil.
Command syntax is as follows:
/opt/fcms/bin/fcmsutil <device_file> lb plm
If the problem persists after verifying fiber optic cabling,
replace the adapter

I had a problem mounting an ocfs2 filesystem under Oracle Cluster Management Software.
root@oracm1:~# mount -a
mount.ocfs2: Transport endpoint is not connected while mounting /dev/mapper/oravg01-lvu03 on /u03. Check ‘dmesg’ for more information on this error.
The error message said to check dmesg for more information and there it was. The cluster was not handshaking with the other node because the network timeout was different.
root@oracm1:~# dmesg

I entered the other cluster node to check the cluster status. The heartbeat is active and the timeout is 10000.

The host oracm1 needs to have exactly the same configuration as oracm2, so I invoked the o2cb script with the configure parameter to reconfigure the timeout.
root@oracm1:~# service o2cb configure

This will configure the on-boot properties of the O2CB driver.
The following questions will determine whether the driver is loaded on

<ENTER> without typing an answer will keep that current value. Ctrl-C
will abort.

I restarted the o2cb service

And checked that the node entered the cluster.

I have a Windows desktop and I was connecting to a Linux server and starting an X11 application where displayed the following “error” message:
Warning: Cannot convert string “-*-lucida-medium-r-*-*-*-*-*-*-*-*-iso8859-1″ to type FontStruct
I downloaded Xming-fonts and this solved the problem for me.

To download the Web Based System Manager client you simply open a browser window and type the URL http://<ip address of your HMC>/remote_client.html.
The Hardware Management Console v7 has web access, so you don’t need to install a client to use it.
