Scripting Help - Blat Script to Notify When Adaptive Copy Tracks < 100MB

vince

is this your system where yon can install tools ? i am running cygwin bash shell on my ECC server. it would be very easy with bash shell to issue symcli command and then filter particular field, check its value and email using windows recource kit utility called postie.

I agree with dynamox. With bash or even Windows Services for UNIX you could easily script with symcli to get data and check for watermark you wish to check. The issue might be scheduling that as Windows are rather poor in that segment (I found several times where Windows native scheduling software didn't work as it should). Mailing this away with blat is easy - I used several times to setup blat to send notification for NetWorker and it works fine. Above mentioned tools are all freeware (which reminds to ask if anyone knows any good and reliable free scheduling software for Windows?).

if you have cygwin installed, you could install crond as a service and use crontab as your scheduler. If you want to get a more sophisticated scheduler that handles multiple dependences then you might want to look at Control-M or Tivoli Maestro..but we are talking serious $$$ there

we just brought up scheduling as another issue ..but with unix based tools you will be able to do exactly what you want.

Thnx! I was not aware crond was available.

Sorry guys, my problem is not with Scheduling. I'd be running this task manually. Scenario is this:

New host coming online that needs to be replicated. I don't want the first replication/sync to take all the bandwidth to DR, so first thing I'll do is put the group in Adaptive Copy mode so as to not affect the R1 host, as well as set QoS on the device group. When I resume replication, I want to be notified that Adaptive Copy tracks are less than 100MB so I can know when we can flip the device group back into Sync mode. Instead of me vpn'ing in every hour to check how far along it is, I'd like an email when invalid tracks are less than 100MB so I can set mode sync.

i'll write a sample bash script so you will see what we are talking about. I am running SRDF semi-sync ..but the idea is the same.

so here is output from symrdf -g RDGROUP query command.

Device Group (DG) Name             : RDFGROUP
DG's Type                          : RDF1
DG's Symmetrix ID                  : 000187700222

Legend for MODES:
 
 M(ode of Operation): A = Async, S = Sync, E = Semi-sync, C = Adaptive Copy
 D(omino)           : X = Enabled, . = Disabled
 A(daptive Copy)    : D = Disk Mode, W = WP Mode, . = ACp off

so i am going to run this script that will loop and query the "R1 Invalid tracks" value, when that value is less than or equal 100, i will send an email and exit the loop.

while true
 do 
   VALUE=`symrdf -g RDFGROUP query|grep "Track(s)"|awk '{print $3}'`
   if [ $VALUE -le 100 ]
   then
    blat.exe - -f vince@blat.com -to vince@blat.com -subject "Vince, vpn in and get back to work !!!"
    exit
   fi
done

piece of cake ...check out http://www.cygwin.com/ ... the only components you need to install is bash shell. Install it on a test system, virtual machines ..or on your own workstation. Let us know, i can show you how to schedule bash script to run from windows scheduler.

Wow - if this works that would be awesome. I'm a pure Windows guy - is this Bash thing complicated?

it's good if you are waiting for some kind of state ...you can't use it to catch when particular field is at particular value.

There is another way to do this....
To save on installing CygWin, you can use "verify" instead of query.

(from the docs)
Verifies whether one RDF device pair or all RDF device pairs in a
device group are in the Synchronized state. Optionally, it can
verify whether the RDF device pair or all device pairs in a device
group are in the Updated state, or in any valid RDF pair state.

The RDF verify action returns the following unique return codes
if the verify criteria was not met:

Code # Code Symbol and Description
4 CLI_C_NOT_ALL_SYNCHRONIZED
5 CLI_C_NONE_SYNCHRONIZED
6 CLI_C_NOT_ALL_UPDATED
7 CLI_C_NONE_UPDATED
14 CLI_C_NOT_ALL_VALID
15 CLI_C_NONE_VALID
31 CLI_C_NOT_ALL_SUSPENDED
32 CLI_C_NONE_SUSPENDED
33 CLI_C_NOT_ALL_FAILED_OVER
34 CLI_C_NONE_FAILED_OVER
35 CLI_C_NOT_ALL_UPDATEINPROG
36 CLI_C_NONE_UPDATEINPROG
37 CLI_C_NOT_ALL_PARTITIONED
38 CLI_C_NONE_PARTITIONED
39 CLI_C_NOT_ALL_ENABLED
40 CLI_C_NONE_ENABLED
41 CLI_C_NOT_ALL_SYNCHRONIZED_AND_ENABLED
42 CLI_C_NONE_SYNCHRONIZED_AND_ENABLED
43 CLI_C_NOT_ALL_SUSP_AND_ENABLED
44 CLI_C_NONE_SUSP_AND_ENABLED
45 CLI_C_NOT_ALL_SUSP_AND_OFFLINE
46 CLI_C_NONE_SUSP_AND_OFFLINE
70 CLI_C_NOT_ALL_CONSISTENT
71 CLI_C_NONE_CONSISTENT

complete list can be taken from reference docs.

here is sample output from my windows machine (its more simple to check and process return values on *nix box).

c:\>symrdf -sid 123 -rdfg 3 -g myGroup verify
None of the device(s) in the list are in 'Synchronized' state.
c:\>echo %ERRORLEVEL%
5
c:\>

Ac active volume that is in Adaptive Copy will never become syncronized, thats why I needed to grep the field when invalid tracks are less than 100MB so that I can safely switch from adaptive copy to async mode.

will a delay help between issuing symrdf?
otherwise it will just loop on that command quiet aggressively...
