Checkmk Werk 12641: dell_compellent_disks: introduce unique item description

ID: 12641 Title: dell_compellent_disks: introduce unique item description Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 The service description for Dell compellent storage disks contained the internal disk number, which unfortunately can change between multiple SNMP-requests. As a result the mapping of disks to services could change and one single disk health status could be reported to changing services. The service description was changed to use the "DELL-STORAGE-SC-MIB::scDiskNamePosition", which contains the enclosure number and the disk number. This scDiskNamePosition will remain stable across multiple SNMP-requests. All services of this plugin must be rediscovered.
