However, I do have a question about one of the blacklist items, specifically the pdisk_cert item. This question arose because I noticed a difference between the way check_openmanage reports a non-Dell certified disk in the "Failure Predicted" condition, depending on whether the disk is connected via an older PERC card (e.g., PERC 6/E) vs. a new PERC card (e.g., H810). I would like to get Trond's and the community's opinion on how the pdisk_cert blacklist item should be interpreted. I am running check_openmanage version 3.7.11/Nagios 3.2.3/Dell OMSA 7.1.0/Ubuntu 12.04. I have two PowerEdge 2950 servers each with their own MD1000. Each MD1000 has a mix of Dell-certified and non-certified disks. One server uses a PERC 6/E card to connect to its MD1000, while the other server uses a PERC H810 card to connect to its MD1000. I am using the same check_openmanage command to check both servers: $USER1$/check_openmanage -H $HOSTADDRESS$ -b pdisk_cert=all On the server with the PERC 6/E card, I got the expected status when a disk was in the "Failure Predicted" state: Physical Disk 0:0:2 [Dell ST31000640SS, 1.0TB] on ctrl 1 is Online, Failure Predicted However, my other server, with the H810 card, also has a disk that Dell OMSA is reporting as "Failure Predicted". Despite that problem I get an "OK" message, using the same check_openmanage command: OK - System: 'PowerEdge 2950 III', SN: 'XXXXXXX', 8 GB ram (4 dimms), 2 logical drives, 17 physical drives If I run check_openmanage without the blacklist, I see the problem disk as: Physical Disk 0:0:13 [Seagate ST31000640SS, 1.0TB] on ctrl 1 is Online, Failure Predicted, Not Certified So, it appears that the "pdisk_cert=all" blacklist is suppressing both warnings about the disk, i.e., the fact that it is "Not Certified" as well as the fact that it is also "Failure Predicted". To get an idea of what I should expect the pdisk_cert blacklist to do, I consulted both the check_openmanage web page( http://folk.uio.no/trondham/software/check_openmanage.html) and the check_openmanage man page. The check_openmanage web page says that the pdisk_cert blacklist will "Ignore warnings for non-certified physical drives". I guess one could interpret that as saying "Ignore *all* warnings related to non-certified physical drives", which would include "Failure Predicted", because that is a "Warning" condition. On the other hand, the check_openmanage man page says that pdisk_cert blacklist will "Suppress warning message about non-certified physical disk." I would interpret the meaning of that a little bit differently, i.e., it will suppress *only* the warning about being non-certified, but report other warnings, e.g., "Failure Predicted". So, here is my question to the people in the Nagios community using check_openmanage with pdisk_cert: Are you expecting that check_openmanage will suppress *all* warnings about non-certified disks or that it will suppress *only* the non-certified warning, but report other warnings, such as "Failure Predicted"? I welcome comments or corrections to my interpretation of the pdisk_cert documentation/behavior.
