I cannot cite the output format of all the NIM-commands from memory, but i think the whole script can be replaced by one NIM-command executed. If you do a mksysb from the NIM server a resource of the type MKSYSB is created and entered into the NIMs database, which can subsequently be queried.
You will have to wait until monday when i return to office for details, but i think it will be possible to replace the whole script with a few select lines of code.
OK, being at the office and sitting in front of an xterm pointing at my NIM server does wonders for that old brain of mine ...
Here it is: you can get a list of all NIM objects of a certain type. In this case you are interested in the resources of type "mksysb". Do yourself a favour and, when you take the mksysb with NIM means, give it a proper name. In my case this means: hostname plus a suffix. Issue:
If you work your NIM-server like me you perhaps have some installation-images as mksysbs which you use to instll new systems (see above, the aix71_04_02) and the images of the various installed LPARs you take regularly (the others in the list above). Now filter out all the installation images so that only the systems are left and cycle through them, using the -l command line option of lsnim to see the details:
Code:
# lsnim -l system_1_mksysb
system_1_mksysb:
class = resources
type = mksysb
creation_date = Sat Oct 15 21:10:56 2016
source_image = system_1
arch = power
Rstate = ready for use
prev_state = unavailable for use
location = /export/mksysb/sys.mksysb
version = 7
release = 1
mod = 3
oslevel_r = 7100-03
oslevel_s = 7100-03
alloc_count = 0
server = master
For instance, a (quick and dirty) code fragment that lists the systems and the creation date of their respective mksysbs, supposing your naming convention is like mine, would be (remove the comments to actually run it):
Code:
lsnim -t mksysb | grep -v '^aix' |\ # filter out install-images
while read MKSYSB junk ; do # read only the mksysb-names
lpar="${MKSYSB%%_mksysb}" # cut off trailing "_mksysb"
cdate=$(lsnim -l $MKSYSB |\ # trim o/p to creation date
sed -n '/creation_date/ s/^.*= //p' \
)
print - "$lpar $cdate" # print results
done
I am aware that this is only the sketch of a solution, but it should be fairly straightforward to implement that into a script.

Hello,
How come the following script adds each numeric value to a total sum ?

A.How the program sums the string "8 8 8" if it`s only the first field value ($1)?
B.If we define x to be $1... (3 Replies)
