Start SAS services at boot

RupaJ — Mon, 19 Nov 2018 21:11:09 GMT

Hello,

Can I use the same instructions to start the SAS services during boot?

@RupaJ,

I suggest you use SAS_lsm: Usage Note 58231: Utility that manages multi-tiered SAS® services for Unix/Linux deployments

Hello @alexal - Apologize for the delay and thanks much for the inputs. I just got to try them. So when I downloaded the script and installed the "Management of multi-tiered SAS services for Unix/Linux deployments V3" , I don't see the file " multi-tier-MCM-94-production.cfg", instead see SAS_lsm.cfg-template. Now the way "SAS_lsm.cfg-template" works is , I will have to provide the tier number to start/stop and that beats the purpose.

./SAS_lsm -o -c SAS_lsm.cfg-template
<<ERROR>> unreadable configuration file [] in [/opt/sas/utilities]

<<USAGE>> [bash | sh] SAS_lsm [-a <NUM> | -o <NUM> | -s] -c <CFG> [-e]

WHERE
-a NUM start deployment tier services from tier NUM to MAXTIERS
-o NUM stop deployment tier services from MAXTIERS to tier NUM
-s provide status of all deployment tier services
-c CFG specify configuration file
-e optionally extract potential tier error logs to a centralized location under !STATUSROOT/!CFG/

NOTE
-a, -o, and -s options are not to be run concurrently

and when I run ./SAS_lsm -o 3 -c SAS_lsm.cfg-template, it stops only the mid-tier and doesn't proceed further. How to I get the multi-tier-MCM-94-production.cfg template. Looks like that's what works.

@RupaJ,

Please open a technical support track and my manager, who created this tool, will be able to assist you.

Assisted! There is support for targeted start and stop in SAS_lsm version 3.0 (available via SASNote 58231). This requires that you specify the tier number that you would like to start from (-a option) or stop to (-o option):

<<USAGE>> [bash | sh] SAS_lsm [-a <NUM> | -o <NUM> | -s] -c <CFG> [-e]

Example given, I have an active three tiered deployment (metadata - 1, compute - 2, middle - 3) and need to address a compute tier issue. Since the metadata tier tier is unaffected. let's keep it running:

To stop: bash SAS_lsm -o 2 ... (stop tier 3 then tier 2)

To restart: bash SAS_lsm -a 2 ... (starts tier 2 then tier 3)
