Desire Z, QuadraSense 1.0

November 19, 2012

HTC Desire Z, smartphone lawas yang sangat berguna buat kerja nih bisa remote sana sini. ROM sudah rooted pakai Andromadus QuadraSense 1.0, turunan Cyanogen yang lite.

Ehm … yang kurang dari QuadraSense nih volume terlalu kecil meski dengan tools tambahan seperti volume rocker.

Hey, we may know how to kill process in unix environment especially the zombie process. All we need is process ID information (PID) and execute ‘kill -9 PID’. But what if those zombie process are hard to be killed & removed? How if we can’t mount a partition and found message “mount: /dev/hdb1 already mounted or /lad/cdma/ busy”

I tried some trick to troubleshoot when found a directory ‘/lad/cdma’ from /dev/hdb1 partition known as read only mode. I already checked /etc/fstab and everything is normal that means no read only mode written in this file configuration. This ‘/lad/cdma’ can’t be remounted.

At last, it can be solved by using this steps,

1. Stop application & database that related to ‘/lad/cdma’
2. Check, kill & trace all process that related to ‘/dev/hdb1’ partition

sh> fuser -m /dev/hdb1
sh> kill -9 PID
sh> strace -p PID

3. Check, kill & trace all process that related to ‘/lad/cdma’

sh>kill -9 PID
sh>strace -p PID

3. Unmount ‘/lad/cdma’

sh> unmount /lad/cdma

4. Remount ‘/lad/cdma’

sh> mount /lad/cdma

Hmm good 🙂

5. Done

It’s a bit confusing when we setup MPXIO storage multipath using old method in Solaris 10 8/11 , and I found panic message and auto rebooted server. Server is only going fine while FC cable was unplugged, it means multipath is failed.

Below I post nice step using new method (it’s too late for me). I hope it can help when we need, especially at critical moment.

Firstly, create backup file

sh> cp /kernel/drv/mpt.conf /kernel/drv/mpt.conf.ori
sh> cp /kernel/drv/fp.conf /kernel/drv/fp.conf.ori
sh> cp /kernel/drv/scsi_vhci.conf /kernel/drv/scsi_vhci.conf.ori


In next step, we must disable internal drive multipath

sh> stmsboot -D mpt -d


We need to check the result,

sh> stmsboot -L
sh> mpathadm list lu


We also have to make sure connected HBA,

sh> luxadm -e port
/devices/pci@0,60/pci@8/SUNW,qlc@0/fp@0,0:devctl         CONNECTED
/devices/pci@1,70/pci@0/SUNW,qlc@0/fp@0,0:devctl         CONNECTED


For example below I use HDS storage. We insert additional line into “/kernel/drv/fp.conf” file,

name="fp" parent="/pci@0,60/pci@8/SUNW,qlc@0" port=0 mpxio-disable="no";
name="fp" parent="/pci@1,70/pci@0/SUNW,qlc@0" port=0 mpxio-disable="no";


Meanwhile, we also have to edit some information line at “/kernel/drv/scsi_vhci.conf” file,

device-type-scsi-options-list="HITACHI DF600F",
"symmetric-option";
symmetric-option = 0x1000000;


Spare 5 minutes or more to review it by your self or ask your friend to do it. After all complete and confirmed, we move to next command to execute the magic command,

sh> stmsboot -e

Have a good day 🙂

Catatan buat Dek Denok sayang,

(I do swear that I’ll always be there. I’d give anything
and everything and I will always care. Through weakness
and strength, happiness and sorrow, for better, for worse,
I will love you with every beat of my heart.)

From this moment life has begun
From this moment you are the one
Right beside you is where I belong
From this moment on

From this moment I have been blessed
I live only for your happiness
And for your love I’d give my last breath
From this moment on

I give my hand to you with all my heart
Can’t wait to live my life with you, can’t wait to start
You and I will never be apart
My dreams came true because of you

From this moment as long as I live
I will love you, I promise you this
There is nothing I wouldn’t give
From this moment on

You’re the reason I believe in love
And you’re the answer to my prayers from up above
All we need is just the two of us
My dreams came true because of you

From this moment as long as I live
I will love you, I promise you this
There is nothing I wouldn’t give
From this moment
I will love you as long as I live
From this moment on

Sebelumnya tidak pernah terjadi problem instalasi via jumpstart seperti ini, “Begin script install_begin execution completed” . Proses instalasi stuck dan tak ada clue penyebabnya. Sehingga problem ini cukup merepotkan, sederhana tapi rumit.

Setelah mencoba beberapa kemungkinan-kemungkinan solusi, akhirnya kita sampai pada kesimpulan bahwa penyebab utamanya adalah disk internal yang contain previous Solaris OS.

Sehingga langkah yang diperlukan sebagai solusinya adalah seperti ini,

1. Boot network to single user mode
“boot net -s”

2. Mengubah layout vtoc internal disk
“format”

3. Execute Solaris installation script
“/sbin/install-solaris”

Dan proses instalasi jumpstart berjalan normal 🙂
