The following steps helped me to backup AIX 5.3 and AIX 6.1 servers.
1st of all, we need to remove the system limits to allow us to create a large file, our backup.
Click here for more information here on IBM website
Edit the limits file:
Allow root user to create unlimited file size by adding “fsize = -1” in its own section:
fsize = -1
We can now run our backup using smitty:
Fill in the path in the first field and change next options if needed. Press Enter to start the backup.
I faced an issue where one of my HP-UX server’s partition became full and won’t let it fully boot. I’ll describe the steps I did the resolve the issue.
- Reboot the server and cancel the HP-UX boot when you get the 10 seconds cool down by pressing any key. On Itanium server, you’ll face the “HPUX >” prompt.
- Boot into single user mode by typing :
HPUX > boot vmunix -is
- The system will boot without any problem this time. Try to mount all File System by typing :
Note : If you get an error saying the File System is corrupted, run “fsck /dev/vg00/lvolX” on the listed partitions. One done, you can mount them again without any problem.
- Once mounted, you gain access to all System commands like “bdf”, “sam”, “ls”, … In my case, using “bdf” showed my /var folder was 100% full.
- I used “sam”, went to “Routine Tasks” menu to clean up/trim old Logs. (mail.log was logging to much errors and consumed too many space, in my case).
- Finally, just issue the “reboot” command and let the server boot normally.
Hope this help.
Scan system for disk:
Get disk info:
Show VG and linked PV:
Show PV info:
pvdisplay -v /dev/dsk/c3t2d0
Check for disk IO error or successful read:
dd if=/dev/rdsk/c3t2d0 of=/dev/null bs=1024k
Enable VG if needed:
vgchange -a y /dev/vg00
Show mount point:
You are also able to manage disk using “sam”.
