SiNgAuTaRa - Live with EMC # NetApp # Solaris # Linux # UNIX

Lesson 1

-It shows 2 HBA card connected to this server from clarion with 14 LUN. If you can see there is 0 errors/dead, so means here each LUN is good connectivity condition to the array or switch.

Lesson 2

-It shows more details of the HBA card and LUN (4 path), all working fine without no errors.

After one month do nothing with my new job, last friday i start my 1st ticket and closed it. mak oiii terer lak guaaa…hehe
Today i learn new stuff, 1st time i ssh to AIX server, jakun plak rasanyaaa..:)
So here some tips that i gather for AIX command, actually not much different with solaris, linux and others unix command but the location of the files distributed somewhere else….:)

-create new user

-delete user

-passwd location files

-group location files

-allow/block remote login

-name service switch

-filesystem mount

-OS level (uname -a)

-timezone

-install soft

-uninstall soft

I’ll will update more form time to time…..hehe

There are sun box using netbackup for DRP backup, monthly backup or daily backup. My previous office, i’m using sun box V240 as backup server connected to quantum PX506 using SCSI wired. Inside PX506 contains 100 tape LTO2 Ultrium (200/400gb) and 4 robot.

Here some tips :

Stopping Netbackup
* /usr/openv/netbackup/bin/K77netbackup –> graceful shutdown
* /usr/openv/netbackup/bin/bpps -a –> check for any remaining processes
* /usr/openv/netbackup/bin/goodies/bp.kill_all —> kills all remaining netbackup process not necessarily graceful
* /usr/openv/netbackup/bin/bpps -a –> check for any remaining processes
* kill -9 {pid} for any remaining. NOTE: unkillable processes may require a reboot PX 506

Starting Netbackup
* /usr/openv/netbackup/bin/S77netbackup –> after bp.kill_all, to restart

Checking Backup Status
* Activity Monitor or
* /usr/openv/netbackup/bin/admincmd/bpdbjobs -report

Here some tips for network configuration and checking using solaris. Normally the you can look inside /etc/system or /etc/rc2.d

- enable network card bge0

- configure IP/netmask and interface up

- check link status

link status 0 = Link Down
link status 1 = Link Up

- check link speed

link speed 0 = 10 Mbps
link speed 1 = 100 Mbps
link speed 1000 = 1 Gbit

- check link mode

link mode 0 = Half-Duplex mode (FDX)
link mode 1 = Full-Duplex mode (HDX)

- check NIC configuration

#ndd /dev/bge0 [apa apa]

Root passwd is important, it must be confidentials.
To delete root passwd, you can go to ok promt. Put cd solaris disk 1 inside the server.

ok> boot cdrom -s

–> mount it to /a or /tmp

- delete g8KeIzST4Un8o
- save and reboot

good info to learn.

- system configuration, memory size, pci

- cpu size and speed

- iostat utility iteratively reports terminal, disk, and
tape I/O activity, as well as CPU utilization

- mpstat reports per-processor statistics in tabular form

- vmstat reports virtual memory statistics regarding process, virtual memory, disk, trap, and CPU activity

-details hardware spec

Let’s says you want to block telnet session, follow details :

then try to telnet, sure cannot. but you still can used other like putty.

I’m having problem with my new server. After sys-unconfig, server seems ‘hang’, i thinks it was IPv4 issues (network interface speed).
Here the failure output :

Sun Fire V240, No Keyboard

The system is coming up. Please wait.
checking ufs filesystems

I need to set up 1000 full duplex (1 giga) for network interface, here the files need to be edit.

Then do normal reboot and check your NIC behind CPU should be blinking.

Actually there are few ways to copy data from filer to another filer.

1) using snapmirror
this method is easily using filerview but need license , so might be expensive. Easily to maintain and the data can be sync automatically.

2) using rsync, so you might need to run with script. What you need to do is mount the location of the filer and destination of the filer inside any server. Then create rsync script and run it as cronjobs.

3) using ndmcopy - this is very simple and easily to used for single data movement. I’ll show you how to do.
Telnet filerA (destination) :

Telnet filerB (source) :

p/s: some user call filer or netapp hostsname.
