rep_opts +.Op Fl P Ar print_opts +.Sh DESCRIPTION +Manage +.Tn SCSI +and +.Tn ATA +Zoned Block devices. +This allows managing devices that conform to the +.Tn SCSI +Zoned Block Commands (ZBC) and +.Tn ATA +Zoned ATA Command Set (ZAC) +specifications. +Devices using these command sets are usually hard drives using Shingled +Magnetic Recording (SMR). +There are three types of SMR drives: +.Bl -tag -width 13n +.It Drive Managed +Drive Managed drives look and act just like a standard random access block +device, but underneath, the drive reads and writes the bulk of its capacity +using SMR zones. +Sequential writes will yield better performance, but writing sequentially +is not required. +.It Host Aware +Host Aware drives expose the underlying zone layout via +.Tn SCSI +or +.Tn ATA +commands and allow the host to manage the zone conditions. +The host is not required to manage the zones on the drive, though. +Sequential writes will yield better performance in Sequential Write +Preferred zones, but the host can write randomly in those zones. +.It Host Managed +Host Managed drives expose the underlying zone layout via +.Tn SCSI +or +.Tn ATA +commands. +The host is required to access the zones according to the rules described +by the zone layout. +Any commands that violate the rules will be returned with an error. +.El +.Pp +SMR drives are divided into zones (typically in the range of 256MB each) +that fall into three general categories: +.Bl -tag -width 20n +.It Conventional +These are also known as Non Write Pointer zones. +These zones can be randomly written without an unexpected performance penalty. +.It Sequential Preferred +These zones should be written sequentially starting at the write pointer +for the zone. +They may be written randomly. +Writes that do not conform to the zone layout may be significantly slower +than expected. +.It Sequential Required +These zones must be written sequentially. +If they are not written sequentially, starting at the write pointer, the +command will fail. +.El +.Bl -tag -width 12n +.It Fl c Ar cmd +Specify the zone subcommand: +.Bl -tag -width 6n +.It params +Display device parameters, including the type of device (Drive Managed, +Host Aware, Host Managed, Not Zoned), the zone commands supported, and +how many open zones it supports. +.It rz +Issue the Report Zones command. +All zones are returned by default. +Specify report options with +.Fl o +and printing options with +.Fl P . +Specify the starting LBA with +.Fl l . +Note that +.Dq reportzones +is also accepted as a command argument. +.It open +Explicitly open the zone specified by the starting LBA. +.It close +Close the zone specified by starting LBA. +.It finish +Finish the zone specified by the starting LBA. +.It rwp +Reset the write pointer for the zone specified by the starting LBA. +.El +.It Fl a +For the Open, Close, Finish, and Reset Write Pointer operations, apply the +operation to all zones on the drive. +.It Fl l Ar lba +Specify the starting LBA. +For the Report Zones command, this tells the drive to report starting with +the zone that starts at the given LBA. +For the other commands, this allows the user to identify the zone requested +by its starting LBA. +The LBA may be specified in decimal, hexadecimal or octal notation. +.It Fl o Ar rep_opt +For the Report Zones command, specify a subset of zones to report. +.Bl -tag -width 8n +.It all +Report all zones. +This is the default. +.It empty +Report only empty zones. +.It imp_open +Report zones that are implicitly open. +This means that the host has sent a write to the zone without explicitly +opening the zone. +.It exp_open +Report zones that are explicitly open. +.It closed +Report zones that have been closed by the host. +.It full +Report zones that are full. +.It ro +Report zones that are in the read only state. +Note that +.Dq readonly +is also accepted as an argument. +.It offline +Report zones that are in the offline state. +.It reset +Report zones that the device recommends should have their write pointers reset. +.It nonseq +Report zones that have the Non Sequential Resources Active flag set. +These are zones that are Sequential Write Preferred, but have been written +non-sequentially. +.It nonwp +Report Non Write Pointer zones, also known as Conventional zones. +.El +.It Fl P Ar print_opt +Specify a printing option for Report Zones: +.Bl -tag -width 7n +.It normal +Normal Report Zones output. +This is the default. +The summary and column headings are printed, fields are separated by spaces +and the fields themselves may contain spaces. +.It summary +Just print the summary: the number of zones, the maximum LBA (LBA of the +last logical block on the drive), and the value of the +.Dq same +field. +The +.Dq same +field describes whether the zones on the drive are all identical, all +different, or whether they are the same except for the last zone, etc. +.It script +Print the zones in a script friendly format. +The summary and column headings are omitted, the fields are separated by +commas, and the fields do not contain spaces. +The fields contain underscores where spaces would normally be used. +.El +.El +.Sh
