Connecting to HP iLO using the command line

Just ssh to the IP that you configured the iLO

HP CLI Commands:

POWER : Control server power.
UID : Control Unit-ID light.
NMI : Generate an NMI.
VM : Virtual media commands.
VSP : Invoke virtual serial port.

Type VSP and you’re in. To login as root you need to include the serial port (in this case ttyS1) on your /etc/securetty file or you will be given the error message that your user or password is wrong.

hpiLO-> VSP

Check if an account is locked on AIX and when was the last time an user logged in

To check account properties you use the command lsuser and specify what property you want to see.

Checking if an account is locked

root@aix:/ # lsuser -a account_locked emerson
emerson account_locked=false

To calculate when was the last time an user logged in to the server, you will need to convert the time displayed. Use the command below to convert.

root@aix:/ # lsuser -a time_last_login emerson
emerson time_last_login=1279036180

root@aix:/ # perl -we ‘print(my $time = localtime 1279036180, “\n”)’

Solaris Error: No utmpx entry. You must exec “login” from the lowest level “shell”

solaris console login: root
Password:
No utmpx entry. You must exec “login” from the lowest level “shell”.

If you encounter this error, login with a regular user, become root and clear the file /var/adm/wtmpx

root@solaris:/var/adm # ls -l wtmpx
-rw-r–r– 1 adm adm 84505380 Jul 4 08:52 wtmpx

root@solaris:/var/adm # > wtmpx

Solaris – ls or df error: cannot canonicalize .: Permission denied

On systems that the umask is set to 027, the directory that is created to be used as a mount point appears to have the correct permissions but you can’t get the disk space utilization or list (ls -la) the permissions of the current directory (.) or the level above (..)

user@solaris:~ $ umask
027

user@solaris:~ $ df -k /backup_export
df: cannot canonicalize .: Permission denied

user@solaris:/ # ls -ld /backup_export
drwxr-xr-x 17 oracle oinstall 1024 Dec 12 15:33 /backup_export

You see that with the root user there is no problem to execute the same command you used as a regular user

root@solaris:~ # df -k /backup_export
Filesystem kbytes used avail capacity Mounted on
/dev/vx/dsk/dadosdg/vol_bkp
92409856 22803105 65256478 26% /backup_export

To solve this problem, umount the filesystem

root@solaris:/ # umount /backup_export

root@solaris:/ # ls -ld /backup_export
drwxr-x— 2 root root 512 Aug 13 2007 /backup_export

Now you apply the permission to make the directory browsable to regular users. I set the permissions to 777 and mounted the filesystem

root@solaris:/ # chmod 777 /backup_export

root@solaris:/ # mount /backup_export

root@solaris:/ # df -k /backup_export
Filesystem kbytes used avail capacity Mounted on
/dev/vx/dsk/dadosdg/vol_bkp
92409856 22803105 65256478 26% /backup_export

The permissions are back to what used to be and now the error message doesn’t appear anymore

user@solaris:~ $ df -k /backup_export
Filesystem kbytes used avail capacity Mounted on
/dev/vx/dsk/dadosdg/vol_bkp
92409856 22803105 65256478 26% /backup_export

Discovering which drives the server will use to boot in a SPARC machine

Here is how to put more than one device on the variable devalias

root@solaris:/ # eeprom “nvramrc=devalias vx-rootdisk /pci@1c,600000/scsi@2/disk@0,0:a (press <Enter>)
> devalias vx-rootmirr /pci@1c,600000/scsi@2/disk@3,0:a” (press <Enter>)

Put more than one device to boot the system

root@solaris:/# eeprom “boot-device=vx-rootdisk vx-rootmirr”

Discovering which disk is used when booting

In the case of this server, it is using vx-rootdisk and if it fails, it will use the next one, the vx-rootmirr

root@solaris:/:> eeprom | grep boot-device
boot-device=vx-rootdisk vx-rootmirr

I need to find the hardware address of these two alias

root@solaris:/:> eeprom | grep vx-root
boot-device=vx-rootdisk vx-rootmirr
nvramrc=devalias vx-rootdisk /pci@1c,600000/scsi@2/disk@0,0:a
devlias vx-rootmirr /pci@1c,600000/scsi@2/disk@3,0:a

Now with the hardware address, I invoke the format command and see that this particular system is using disks 2 and 5 to boot.

root@solaris:/:> echo | format
Searching for disks…done

Specify disk (enter its number): Specify disk (enter its number):

To create the alias as stated in the beginning of this post, it will be necessary to get the hardware address and replace “sd” for “disk”.
Also Specify which disk slice that holds the root (/) filesystem. The slice 0 is the letter a, the slice 1 is b and so on.

To validate this hardware address use boot and specify it on the OpenBoot prompt

ok> boot /pci@1c,600000/scsi@2/disk@3,0:a

Starting an Oracle database instance

Here is a reference if I need to start an Oracle database instance. It may not be the best way but this is how I done.

I became the user oracle

root@solaris:/ # su – oracle

Exported the variable that sets the instance that I’ll deal with

oracle@solaris:~ $ export ORACLE_SID=testing

Started sqlplus

Reattach plex to the volume in Veritas Volume Manager

Some systems have the boot disk encapsulated in Veritas and it is mirrored

root@solaris:/ # vxprint -htg rootdg -v rootvol
V NAME RVG KSTATE STATE LENGTH READPOL PREFPLEX UTYPE
PL NAME VOLUME KSTATE STATE LENGTH LAYOUT NCOL/WID MODE
SD NAME PLEX DISK DISKOFFS LENGTH [COL/]OFF DEVICE MODE
SV NAME PLEX VOLNAME NVOLLAYR LENGTH [COL/]OFF AM/NM MODE

v rootvol – ENABLED ACTIVE 14338107 ROUND – root
pl rootvol-01 rootvol ENABLED ACTIVE 14338107 CONCAT – RW
sd rootdisk-B0 rootvol-01 rootdisk 71124290 1 0 c0t0d0 ENA
sd rootdisk-02 rootvol-01 rootdisk 0 14338106 1 c0t0d0 ENA

This volume should have at least two plexes, so there are plexes currently disabled on this disk group.

root@solaris:/ # vxprint -htg rootdg | grep DISABLED
pl local-02 – DISABLED – 6292242 CONCAT – RW
sd rootmirr-09 local-02 rootmirr 51897995 6292242 0 c0t1d0 ENA

pl rootvol-02 – DISABLED – 14338107 CONCAT – RW
sd rootmirr-01 rootvol-02 rootmirr 2888 14338107 0 c0t1d0 ENA

To attach this plex to the volume type the command below

root@solaris:/ # vxplex -g rootdg att rootvol rootvol-02

Veritas will not release the shell until it completes the task. Open another terminal and type vxtask list to check the status

root@solaris:/ # vxtask list
TASKID PTID TYPE/STATE PCT PROGRESS
180 ATCOPY/R 60.16% 0/14338107/8626432 PLXATT rootvol 0.0

After it is finished, check the volume again. It should have two plexes like in the example below

root@solaris:/ # vxprint -htg rootdg -v rootvol
V NAME RVG KSTATE STATE LENGTH READPOL PREFPLEX UTYPE
PL NAME VOLUME KSTATE STATE LENGTH LAYOUT NCOL/WID MODE
SD NAME PLEX DISK DISKOFFS LENGTH [COL/]OFF DEVICE MODE
SV NAME PLEX VOLNAME NVOLLAYR LENGTH [COL/]OFF AM/NM MODE

v rootvol – ENABLED ACTIVE 14338107 ROUND – root
pl rootvol-01 rootvol ENABLED ACTIVE 14338107 CONCAT – RW
sd rootdisk-B0 rootvol-01 rootdisk 71124290 1 0 c0t0d0 ENA
sd rootdisk-02 rootvol-01 rootdisk 0 14338106 1 c0t0d0 ENA
pl rootvol-02 rootvol ENABLED ACTIVE 14338107 CONCAT – RW

Two examples of using dumpadm on Solaris

I run dumpadm and saw that two things needed to be changed. The savecore directory and the dump device.

root@solaris:/ # dumpadm
Dump content: kernel pages
Dump device: /dev/dsk/c0t0d0s1 (dedicated)
Savecore directory: /var/crash/old_hostname
Savecore enabled: yes

To change the savecore directory, use the flag -s and specify the directory that you wish to use when Solaris need to save the crash dump file

root@solaris:/ # dumpadm -s /var/crash/solaris
Dump content: kernel pages
Dump device: /dev/dsk/c0t0d0s1 (dedicated)
Savecore directory: /var/crash/solaris
Savecore enabled: yes

Now, to change the dump device you pass the flag -d and the device to save the crash dump file

root@solaris:/ # dumpadm -d /dev/md/dsk/d1
Dump content: kernel pages
Dump device: /dev/md/dsk/d1 (swap)
Savecore directory: /var/crash/solaris
Savecore enabled: yes

How to replace the ball top for a bat top on a Mad Catz Street Fighter IV FightStick Tournament Edition

If you are looking for a video teaching how to replace the ball top of a Mad Catz Street Fighter IV FightStick Tournament Edition look no further. You’ll need a Sanwa LB-30-N Joystick Bat Top and Sanwa Joystick Adapter. I bought my parts from Lizard Lick.

To replace the ball top for a bat top, you will need to remove all the hex screws and open the top of your FightStick. On the bottom of the joystick, put a knife or a flat screwdriver and loose the ball top.

Watch the video around 4m10s to see what’s the procedure looks like.
