[dtrace-discuss] dtrace doesn''t work for comstart iscsi
Hello,
I need some advise in sorting out the weird issue: dtrace works fine for 3
servers, but doesn''t on the 4th one.
I''m tracing iscsi initiators activity with it. As everybody knows,
dtrace doesn''t work out of the box for comstar, only after copying
iscsi.d into /usr/lib/dtrace/ from another server.
It''s copied but still no luck. Is there is a way to figure out why it
doesn''t work on this particular server which is a clone of others?
#uname -a
SunOS zsan03 5.11 snv_118 i86pc i386 i86pc Solaris
#dtrace -n ''iscsi:::data-* { @[probename] =
sum(args[1]->ii_datalen); }''
dtrace: description ''iscsi:::data-* '' matched 5 probes
#dtrace -l -n ''iscsi*:::''

Hi Roman: What is the error you get ? That might help pinpoint to the problem -Angelo On Oct 21, 2009, at 10:31 PM, Roman Naumenko wrote:> Hello, > > I need some advise in sorting out the weird issue: dtrace works fine > for 3 servers, but doesn''t on the 4th one. > > I''m tracing iscsi initiators activity with it.
