This fixes some unusable services of the "HPE Proliant Servers: Raid Status" plugin. This werk only affects you if you observe unknown "Logical device <ITEM>" 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 "\x00" (the null-byte) as their name (OID .

Not all components delt well with it, leading to unacknowlegable downtimes, non matching rules and the like. We now replace all null-bytes with "\\x00" (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 monitoring history by running

sed -i 's|\x00|\\x00|' var/check_mk/core/history var/check_mk/core/archive/*
