Solaris 10 new feature on NIC status

Sun, 14 Sep 2008 11:23:43 GMT

dladm is meaning Administer Data Link. This feature is a new faeture that I can see on Solaris 10 compare to other version. Before this, I've to make a script to have the status of NIC in easy way.

This command also can rename the device, associate the device, remove device, connect server to WiFi, configure the aggregration and create the VLan

# dladm show-dev
e1000g0         link: up        speed: 1000 Mbps       duplex: full
e1000g1         link: down      speed: 0     Mbps       duplex: half
e1000g2         link: down      speed: 0     Mbps       duplex: half
e1000g3         link: down      speed: 0     Mbps       duplex: half

# dladm show-link
e1000g0         type: non-vlan mtu: 1500       device: e1000g0
e1000g1         type: non-vlan mtu: 1500       device: e1000g1
e1000g2         type: non-vlan mtu: 1500       device: e1000g2
e1000g3         type: non-vlan mtu: 1500       device: e1000g3

System identification is completed.

        This system is configured with NFS version 4, which uses a domain
        name that is automatically derived from the system's name services.
        The derived domain name is sufficient for most configurations. In a
        few cases, mounts that cross different domains might cause files to
        be owned by "nobody" due to the lack of a common domain name.

Do you need to override the system's default NFS version 4 domain
name (yes/no) ? [no] : no

        For more information about how the NFS version 4 default domain
        name is derived and its impact, refer to the man pages for nfs(4)
        and nfsmapid(1m), and the System Administration Guide: Network
        Services.

AIX - SENDMAIL

Tue, 20 May 2008 11:02:00 GMT

There's few way to restart you sendmail in AIX.

1. # refresh -s sendmail
2. # sendmail -bi
3. # sendmail.cf stop
# sendmail.cf start
4. # stopsrc -s sendmail
# startsrc -s sendmail

If you discover that the sendmail daemon dies after you started it. You have to pass the parameters to sendmail to start it correctly. So best would be:

# stopsrc -s sendmail
# startsrc -s sendmail -a"-bd -q30m"

If you only need to refresh the configuration you can also run:

# refresh -s sendmail

Hazrul Wedding

Wed, 23 Apr 2008 08:31:18 GMT

Early of this month, I have attended my buddy wedding in JB. I think this is my 3rd time I have been in JB and 1st time drove to be there.

About 400KM, it is taking 3 hours driving and exactly after I had finished my works at 10pm. In JB, I was lost for about 1 hours looking to Seri Malaysia Hotel and damn.... all rooms are occupied. So, I have no chooice to stay-up in expensive hotel that cost me 350 per night. But, they had giving me a very nice room with king size bed, so my night is very comfortable.

The room check-out is actually at 3pm, but I do early check-out at 12PM so I can be at venue at 1PM... Women house - the venue, I've been told by my buddy that he will only arrived around 2PM, so I decide to spent my time at Giant Hypermarket. They then only showing their faces at 2.40PM.

Happy Face... The arrival for man late.. But it is always in Malay tradition

Before you can see the women... Please pay the toll Here, man need to pay the toll twice, the last toll gate girl are very brutal.

At last, the man meet the women. At the thorn. Hazrul, you look so serious buddy.

Finally, eating time...

At 3.30PM, I already move out back to KL... The clouds already turn to dark at those time, so I think better I move out early before I stuck in jam in JB.

Yamaha The Curve

Mon, 18 Feb 2008 01:22:33 GMT

Last Saturday, I was attending to see a live jam perform by my colleague - Fauzan and his friend at Yamaha in the Curve shopping complex.

To see him playing a guitar live was really nice and enjoyable. Overall it is okay, only his guitar sound is taken over by drums and piano. His guitar should being set louder. Anyway nice one Pozan.... Hope can see you in other more bigger perfomance.

How to confirm new SAN disk in AIX

Thu, 15 Nov 2007 14:02:25 GMT

Usually from SAN storage, LUN number will be given in decimal number. Let say you are working in big organization and using a enterprise storage like Hitachi or EMC. When you request a space from SAN/Storage administrator, they might be reply to you with below message.

Allocated 90GB (1x50gb,2x20gb) for serverA on hitachi-9990. Lun number is 26-28 (dec).Lun already visible on the server.

So, how do you will know that those LUN is available in your server?

In AIX, to detect a new device is using cfgmgr commmand. HPUX will using ioscan and Solaris will using devfsadm. Something good about AIX, it will not required server to be reboot to detect new hardware. Assume that you running below command and hardware scanning on server is completed.

serverA:/#cfgmgr -v

Next is to convert Decimal number to HEX number. This because in AIX it is will showing in HEX number. How to change from DEC to HEX? Use you scientific calculator or in easy way, your windows already providing scientific calculator for you.

Type the DEC number on calculator.

Then click button from DEC to HEX.

Now you can start comfirming on your server using lscfg command. Example from culcalator above, HEX number is 1A. Now, run command and grep the 1A.

serverA:/#lscfg -v | grep 1A
hdisk41          U787B.001.DNWD28D-P1-C1-T1-W50060E80047D9842-L1A000000000000 Hitachi Disk Array (Fibre)
hdisk38          U787B.001.DNWD28D-P1-C4-T1-W50060E80047D9850-L1A000000000000 Hitachi Disk Array (Fibre)
        Product Specific.(Z0).......571A
        Customer Card ID Number.....571A
        Customer Card ID Number.....571A

Now you can confirm from physical volume that those hard disk is visible in OS level by using command lspv. As below showing hdisk38 and hdisk41 is now visible in OS level.

serverA:/# lspv
hdisk0          000da9d0c97dfdc6                    rootvg          active
hdisk1          000da9d0c97dfe2b                    rootvg          active
hdisk2          none                                VeritasVolumes
hdisk3          none                                VeritasVolumes
------------------------------- more -------------------------------------
hdisk38         none                                none
hdisk39         none                                none
hdisk40         none                                none
hdisk41         none                                none
hdisk42         none                                none
hdisk43         none                                none

Now you can see that hdisk41 is a disk with HEX number 1A. But why it is showing 2 hard disk? This because your server is having 2 HBA card pointing to same source. Why? Because for failover. Let say if 1 fiber cable or HBA card down, then you are still having another 1 link running.

How to confirm you server is having 2 HBA? Run command #lsdev as below. Result will showing below output that server is having 2 HBA. But, we still need to confirm is it using for disk failover. This is because sometimes, second HBA being use for other purpose like connecting server to Tape Media Storage.

serverA:/# lsdev -C | grep fc
fcnet0         Defined   04-08-01      Fibre Channel Network Protocol Device
fcnet1         Defined   06-08-01      Fibre Channel Network Protocol Device
fcs0           Available 04-08         FC Adapter
fcs1           Available 06-08         FC Adapter

Above is showing that 'card 0' is 04-08-01 and 'card 1' is 06-08-01. Now, run command #lsdev -Cc disk to show hard disk path. Now you can see that hdisk38 is running on 04-08-02 and hdisk41 running on 06-08-02. So that mean hdisk38 is using card 0 and hdisk41 is using card 1.

serverA:/# lsdev -Cc disk
hdisk0 Available 02-08-01-3,0 16 Bit LVD SCSI Disk Drive
hdisk1 Available 02-08-01-4,0 16 Bit LVD SCSI Disk Drive
hdisk2 Available 02-08-01-5,0 16 Bit LVD SCSI Disk Drive
hdisk3 Available 02-08-01-8,0 16 Bit LVD SCSI Disk Drive
hdisk4 Available 04-08-02     Hitachi Disk Array (Fibre)
hdisk5 Available 04-08-02     Hitachi Disk Array (Fibre)
hdisk6 Available 04-08-02     Hitachi Disk Array (Fibre)
------------------------ more ---------------------------
hdisk38 Available 04-08-02     Hitachi Disk Array (Fibre)
hdisk39 Available 04-08-02     Hitachi Disk Array (Fibre)
hdisk40 Available 04-08-02     Hitachi Disk Array (Fibre)
hdisk41 Available 06-08-02     Hitachi Disk Array (Fibre)
hdisk42 Available 06-08-02     Hitachi Disk Array (Fibre)
hdisk43 Available 06-08-02     Hitachi Disk Array (Fibre)

Again as reminder.. To confirm if this hard disk is on failover link or if it is running in single HBA, run command #lscfg -v and grep to HEX number to see if it output showing 1 hard disk or 2 hard disk. If 2 hard disk, then it is running on 2 HBA (failover).

Fujitsu Server.

Sun, 11 Nov 2007 08:15:50 GMT

Do you have heard about Fujitsu UNIX server? Yup, it is Fujistu Machine that running Solaris OS on it. There's 2 types of Fujitsu UNIX server - Sparc Enterprise and PRIMEPOWER.

Hmmm.. Solaris running on Sparc processor? Better we buy the SUN product . Before this I had work with another Japanese product, Hitachi server that are running with HPUX OS. Actually, I am not sure what is difference between this Fujitsu and SUN server. Like below M9000 server, SUN also having M9000. So it is only a OEM product or Fujitsu had change something making it better then SUN.

Last week, our customer server is having some issue and this Fujitsu guy is asking to run snap to look for the error. My manager had foward this to us for somebody to working with it. It is called fjsnap. It is quite similar to explorer file for Solaris, but this fjsnap is also working on their product for linux and windows servers. This command will capture the system for any error. File then created and we will ftp to the server. The engineer later will analyze the file looking for any error.

I had run

/opt/FJSVsnap/bin/fjsnap/fjsnap -T /tmp /tmp/fujidata/123445

-T /tmp is a temporary place for data to be locate whole it is running and then /tmp/fujidata/123445 is where fjsnap output will be place. I had choose number (example 123445) where it is refer to our case ID.

Below is option where you want fjsnap to capture everything on server.

/opt/FJSVsnap/bin/fjsnap/fjsnap -a T /tmp /tmp/fujidata/123445

Pilot, Stewardess and Computer

Wed, 31 Oct 2007 12:59:18 GMT

It is a long time I not visiting this place. Last time I always being here. This place is having 2 blocks, training building and computer building. There is lot of memories here.

This training building is belongs to MAS Academy. Most training for MAS staff is done here. Computer building is place where datacenter for Malaysia Airlines is located. Everything about computer center for MAS is pointed in here.

This building also provide spaces for other company like Heitech Padu – for their Business Recover Center and also Celcom – where I think it is related to communication that they had provide to MAS when TR was heading this both MAS and Celcom.

Previously I was working in Heitech Padu Bhd. as a HP UNIX DR engineer. This Business Recovery Center is providing customer to have a machine and other facilities for them to place their COLD data and also doing a testing for disaster recovery. My wife is working Heitech Padu too. She is IBM Mainframe engineer and the time I visiting this building, she actually having a recovery testing for National Registration Department.

I still remember when having food at MAS cafeteria, all stewardess will greeting me and others. I’ve been told because I’m wearing a formal with necktie, so they thought we are pilot J

I’m crazy with planes. When the time I re-visit the training building, there are so much plane model in huge size at this building. I wish me having 1 of it at my home. Ehehehehe….
