In this posting, we will learn how to create Filesystem on IBM AIX. If we have a cluster system, then we need to create the same filesystem definition in all servers that used in cluster system. For this reason, we only exportvg in a server and import it to another servers.

To Extend Logical Volume :
Scenario :
Increase size of /backup to 90GB
 

$ df -H
 Filesystem              Size   Used  Avail Use% Mounted on
 /dev/mapper/vg00-lvol01 6.3G   187M   5.8G   4% /
 /dev/mapper/vg01-lvol02 8.3G   3.0G   5.0G  38% /archive
 /dev/mapper/vg01-lvol03  83G    11G    69G  13% /backup

If we using Storage Area Network (SAN) with FC,  SAN can do scanning  all connected FC in the SAN Switch. From SAN storage we can get the World Wide Name (WWN) of the HBA –each HBA has unique WWN (same as MAC Address in the PC), but if there are many servers connected the FC into the same SAN Switch, might be we can get difficulties which server has particular WWN.

In this topic I only discuss how to know the WWN of the HBA in HP-UX server. Continue reading »

 

To monitor event in HP-UX server, first we must install and running Event Monitoring Services(EMS). After that we can use monconfig (a utility that allows a superuser to manage hardware event monitor requests for EMS).

In this working note, I will show you the example steps through creating a monitor request and sending any alerts that are greater than or equal to (>=) “Major Warnings” to an EMAIL address Continue reading »

 

To get to single user mode, if you’re using LILO, type:
Code:

        linux single

at the boot prompt and hit ENTER.

If you’re using GRUB, hit ENTER at the countdown screen (booting kernel-whatever in 10 seconds…), select your kernel from the menu (the line that starts with “kernel”) and hit e. At the end of the line, add:
Code:

Accessing Linux from XManager :

  1. Edit gdm.conf
    • vi /etc/X11/gdm/gdm.conf
  2. on the section [xdmcp], set the value Enable=true (default is ‘False’)
  3. Restart the service of gdm
    • killall gdm-binary
  4. And now you can access Linux console from XManager.
 

To Check the LUN
#spmgr display

#ioscan -nfCdisk

#insf -e

#ioscan -nfCdisk

Cek  /etc/lvmtab ( Yang tidak ada berarti milik EVA yang baru)

#diskinfo /dev/rdsk/C******
diskinfo /dev/rdsk/c14t4d0
diskinfo /dev/rdsk/c14t4d1
diskinfo /dev/rdsk/c14t4d2 Continue reading »
