SAR -d issue with storage
Hello forum,
I'm newbie on this topic and this forum.
I've an issue (?) with my system and/or IO monitoring. In particular my system is an HP Superdome2 with HP-UX 11.31 OS.
In order to monitor IO usage we utilize SAR, out-of-the-box with the OS.
What we are noting during the last days is a quite strange SAR -d behaviour. That is two or three times per day the output of SAR -d is so far away from the physical range normal IO behaviour: we have r+w/s near 35 million and blks/s over 650 millions.
The SAR version is:
/usr/sbin/swlist -l file |grep -i "/usr/sbin/sar" OS-Core.SYS2-ADMIN: /usr/sbin/sar PHCO_42120.SYS2-ADMIN: /usr/sbin/sar
Below there is a sample of the described output:
<CMD-015;20140210120209;xxx;/usr/bin/sar -d 30 1 > HP-UX xxx B.11.31 U ia64 02/10/14 12:02:09 device %busy avque r+w/s blks/s avwait avserv 12:02:39 disk12 1.13 0.50 38 667 0.00 0.35 disk13 0.00 0.50 0 0 0.00 0.15 disk14 1.00 0.50 34 648 0.00 0.36 disk305 0.00 0.50 0 0 0.00 2.33 disk306 100.00 0.50 480183 10214909 0.00 1.83 disk307 0.00 0.50 0 0 0.00 2.53 disk308 0.03 0.50 0 0 0.00 4.54 disk309 0.03 0.50 0 0 0.00 5.64 disk310 0.00 0.50 0 1 0.00 1.18 disk311 0.13 0.50 0 11 0.00 3.98 disk312 0.07 0.50 0 4 0.00 4.46 disk313 0.00 0.50 0 0 0.00 2.51 disk314 0.07 0.50 0 1 0.00 7.97 disk315 0.03 0.50 0 0 0.00 2.38 disk316 0.07 0.50 0 9 0.00 9.98 disk317 0.10 0.50 1 98 0.64 7.49 disk318 0.03 0.50 0 0 0.00 7.23 disk319 0.00 0.50 0 0 0.00 2.37 disk320 0.00 0.50 0 0 0.00 0.92 disk321 100.00 0.50 59491 7240524 0.01 5.02 disk322 0.00 0.50 0 0 0.00 2.35 disk323 0.03 0.50 0 0 0.00 2.45 disk324 0.03 0.50 0 0 0.00 4.55 disk325 0.03 0.50 0 0 0.00 2.30 disk326 0.00 0.50 0 0 0.00 2.39 disk327 0.03 0.50 0 0 0.00 2.08 disk328 6.23 0.51 128 1275 0.01 0.79 disk329 0.00 0.50 0 0 0.00 2.74 disk330 0.00 0.50 0 0 0.00 1.82 disk331 0.03 0.50 0 0 0.00 2.73 disk332 0.03 0.50 0 0 0.00 1.98 disk333 0.03 0.50 0 0 0.00 1.99 disk334 0.00 0.50 0 0 0.00 2.80 disk335 0.00 0.50 0 0 0.00 2.97 disk336 0.17 0.50 2 64 0.00 2.50 disk337 1.03 1.31 16 115 0.61 1.18 disk338 0.03 0.50 0 0 0.00 3.80 disk339 0.00 0.50 0 0 0.00 3.88 disk340 0.00 0.50 0 0 0.00 2.03 disk341 0.03 0.50 0 0 0.00 4.28 disk342 0.03 0.50 0 0 0.00 5.40 disk343 0.03 0.50 0 0 0.00 5.21 disk344 0.00 0.50 0 0 0.00 2.33 disk345 0.00 0.50 0 0 0.00 2.17 disk346 0.00 0.50 0 0 0.00 2.40 disk347 0.03 0.50 0 0 0.00 5.47 disk348 0.00 0.50 0 0 0.00 3.49 disk349 0.00 0.50 0 0 0.00 5.41 disk350 0.03 0.50 0 0 0.00 2.13 disk351 0.00 0.50 0 0 0.00 8.02 disk352 0.03 0.50 0 0 0.00 8.38 disk353 0.00 0.50 0 0 0.00 3.83 disk354 0.00 0.50 0 0 0.00 4.16 disk355 0.03 0.50 0 0 0.00 5.39 disk356 0.00 0.50 0 0 0.00 2.25 disk357 0.00 0.50 0 0 0.00 2.09 disk358 0.00 0.50 0 0 0.00 2.13 disk359 0.00 0.50 0 0 0.00 4.26 disk360 0.00 0.50 0 0 0.00 3.60 disk361 0.03 0.50 0 0 0.00 5.20 disk362 100.00 0.50 50281 17233818 0.02 4.46
My question is: it could be a SAR bug for this version ? Otherwise could I investigate more then storage and hd ?
Thanks in advance

Re: SAR -d issue with storage
Hi likid0,
the current cumulative patch installed is PHCO_42120: it seems to be the last one realeased by HP.
Moreover I've verified that this patch could solve so many issues with sar -d, it introduces new problem with sar indeed.
Another server with the same OS version, patch and application doesn't give this kind of problem.
It is very frustrating
Luigi

Re: SAR -d issue with storage
If you have the latest and greatest in sar cumulative patch, I would try and compair the sar results with another tool, if you have glance or Performance Agent, leave them running and compair the results with sar outputs.

Re: SAR -d issue with storage
Hi,
unfortunately I don't have another tool to monitor IO resource, and in general all resoruces. In any case I can stated that there is a inaccuracy issue related to SAR output values, these values are not physical acceptable for any storage devices: IOPS 10 million and Throughput over 250M MB/s.
I suppose that there is an issue concerning SAR and/or OS. For that I'm asking if anyone also did face this situation ?
