mksysb -ieX /path_to_take_backup This command will create AIX mksysb backup with excluded content.
mksysb -iX This will create full backup of AIX OS.
-i mksz command called to create image.data file.
-e check /etc/exclude.rootvg and exclude required file from backup
-X expand /tmp dynamically if needed
Mirroring AIX rootvg to hdisk1
extendvg rootvg hdisk1

Command To list devices on AIX
cfgmgr Detect new device on AIX
lsdev List all devices on AIX LPAR
lsdev -Cc disk Show disk information on AIX
lsdev -Cc adapter |grep -i fcs show only FCS adapter information
lsdev -Cc adapter |grep -i ent show only ethernet adapter information
lscfg -vl fcs0 | grep Network display wwn of fcs0 adapter
Performance Monitoring
For monitoring performance of AIX LPAR admin can use command like topas,nmon,svmon,ipcs ,vmstat and df .
topas Monitor top process which are consuming system resources ,also can monitor paging space ,memory and CPU utilization
while topas is running if admin press ~ (tild) then topas switch to nmon mode.
nmon This command also show information like ,CPU ,Memory and paging
space.
lsps -s Show paging space utilization.
# svmon -P -O summary=basic,unit=MB Virtual memory stats in Mb
#vmstat 2 5 Show five output at interval of 2 second.it contains CPU and memory utilization.
ipcs Report interprocess communication information like shared memory,semaphore and queue details.
-s semaphore
-m memory
q- message queue
will update new command .............
bootlist -m normal -o It will display bootlist for AIX server.
example
#bootlist -m normal -o
output :
hdisk0 blv=hd5 pathid=0
bootlist -b Show last boot device from which AIX LPAR booted.
bootlist -m normal hdisk0 blv=hd5 hdisk1 blv=hd5 This command change bootlist to hdisk0 and hdisk1
AIX file system utilization command
df -gt This command display all filesystem which are mounted on AIX server.
df -gt /fsname Display specific filesysetm disk utilization.
-g show File system utilization in GB unit
-m show File system utilization in MB unit
