SysAdmin received this email, looks like the request has been escalated to my boss.
Could you please assist Matt ASAP! This is pertaining to UNIX acct so we need to iron out.
The SC is 14270227.
Make this high priority please.
root filesystem (/) is currently 100% full. Quick Response Team require free disk space to perform some activities on the particular filesystem. Therefore, Unix team have to free up some space or extend the filesystem. Due to the fact that it is hard to perform housekeeping, i chose the second method.
root 3 /tmp> uname -a; date; uptime AIX xXxXx 3 4 0056BA6A4C00 Wed Sep 3 17:37:25 DFT 2008 05:37PM up 387 days, 10:46, 3 users, load average: 1.10, 1.05, 1.05
Disk space usage (before filesystem extension)
root 3 /tmp> df -k / Filesystem 1024-blocks Free %Used Iused %Iused Mounted on /dev/hd4 16384 0 100% 1329 17% /

Extending the space of LV & filesystem by 16MB,
root 3 /> extendlv hd4 1 root 3 /> chfs -a size=65536 / File System size changed to 65536
Note: size=65536, the unit is in 512 byte blocks which is equal to 16MB
