[2.2.0] Checkmk Werk 16274 created: Unusable services for "HPE Proliant Servers: Raid Status"

Title: Unusable services for "HPE Proliant Servers: Raid Status" Class: fix Compatible: incomp Component: checks Date: 1702636533 Edition: cre Level: 1 Version: 2.2.0p18 This fixes some unusable services of the "HPE Proliant Servers: Raid Status" plugin. This werk only affecs you if you observe unknown "Logical device &lt;ITEM&gt;" services after the upgrade. In case you are affected please run a discovery on the affected hosts and fix the monitoring history as described below. We observed some devices to send <tt>"\x00"</tt> (the null-byte) as their name (OID .1.3.6.1.4.1.232.3.2.3.1.1.14). Not all components delt well with it, leading to unacknowlegable downtimes, non matching rules and the like. We now replace all null-bytes with <tt>"\x00"</tt> (the literal containing the four characters backslash, 'x', 'zero', 'zero'). As of Checkmk 2.3, this should in fact no longer be necessary, but as we need a backportable solution, we change the item consistently in all versions. If this affects you, you might also want to fix the services in the monitring history by running C+: sed -i 's|\x00|\\x00|' var/check_mk/core/history var/check_mk/core/archive/* C-:
