Hi Lennart,
I played around with the patch and some comments below:
1) For the below cases, if the OM is not yet supporting printing of error
strings from OI, then
On top of saImmOiCcbSetErrorString(), We may also want to print the error
messages aditionally to syslog,
+ TRACE("logStreamSystemHighLimit validation Fail");
+ TRACE("logStreamSystemLowLimit validation Fail");
+ TRACE("logStreamAppHighLimit validation Fail");
+ TRACE("logStreamAppLowLimit validation Fail");
+ TRACE("Cannot change attributes. Not supported by
standby");
2) In, lgs_imm_rootpathconf_set()
we could avoid the error string "lgsv root path is changed to "
i.e. when i try to change the root directory, then the following multiple error
strings are observed, we could avoid one of them:
Aug 5 18:19:12 SC-1 local0.err osaflogd[397]: ER Old log files could not be
renamed and closed, root-dir: /repl_opensaf/saflog
Aug 5 18:19:12 SC-1 local0.err osaflogd[397]: ER Old log files could not be
renamed and closed, root-dir: /repl_opensaf/saflog
Aug 5 18:19:12 SC-1 local0.notice osaflogd[397]: NO lgsv root path is changed
to "/repl_opensaf/mathi"
Aug 5 18:19:12 SC-1 local0.notice osaflogd[397]: NO Log root directory changed
to: /repl_opensaf/mathi
3) In the case when highlimit is equal to low limit, should we really consider
that as an error?
error - saImmOmCcbApply FAILED: SA_AIS_ERR_FAILED_OPERATION (21)
OI reports: HIGH limit <= LOW limit
Thanks,
Mathi.
