Reserved slots 17 Configuring the extended library The extended library appears to the host as a single library. The upper Library is always the master Library. Reserved slots can be accessed by the RMI or OCP, but are invisible to the host and backup software. For example, you might keep a cleaning cartridge in a reserved slot if your backup software does not manage the cleaning process. Default settings The maximum number of reserved slots is the total number of storage slots minus 2.
