Need help?Do you have a question about the QNAP SAS JBOD CLI 1.0 and is the answer not in the manual?
The provided document is a User Guide for the QNAP SAS JBOD CLI 1.0, specifically for models TL-R1220Sep-RP and TL-R1620Sep-RP. This guide details how to set up access to the Command-Line Interface (CLI) and provides a comprehensive list of commands for configuring and managing the SAS JBOD enclosures.
The QNAP SAS JBOD enclosures are storage devices that come equipped with a Command-Line Interface (CLI). This CLI allows users to configure and manage the enclosures from a terminal emulator on various operating systems, including Windows, macOS, and Linux. The primary function of the CLI is to provide a text-based interface for detailed control over the JBOD's physical layers, system information, fan speed, disk location, buzzer, and zoning configurations. It enables administrators to perform tasks that might not be available or as granular through a graphical user interface, offering a powerful tool for system customization and troubleshooting.
While the document does not explicitly list all technical specifications of the JBOD hardware itself (such as storage capacity, drive types supported, physical dimensions, or power consumption), it does provide insights into the capabilities and parameters configurable via the CLI.

link command allows for displaying and setting the maximum and minimum speed of physical SAS links.phyinfo command displays detailed information about physical layers, including link rates and attached SAS addresses.System Information:
systeminfo command provides details such as the number of bays (e.g., "16 Bay system"), number of power supplies ("Power num: 2"), number of fans ("Fan num: 3"), machine type ("SAS JBOD"), enclosure firmware version (e.g., "FW V 1.14.0.14"), vendor ID ("QNAP"), and model (e.g., "TL-R1620Sep").system status command displays chip and enclosure controller (ENC) temperatures (e.g., "Chip Temp: 60C", "ENC1. Temp: 21C").SAS Addressing:
sasaddr command displays the SAS addresses of connected ports, providing unique identifiers for the expander SAS ports (e.g., "SxP Port 0 SAS Address: 0x5E843B61001ADFFD").Physical Layer Counters:
counters command allows displaying error and generic broadcast counters for physical layers, including InvWrdCnt, DispErrCnt, LossSyncCnt, and RstSeqFailCnt. These counters are crucial for monitoring the health and performance of SAS links.Zoning:
phyzone command enables configuration of zoning information, allowing for the creation of groups and assignment of slot numbers and SAS ports. This is a critical feature for controlling access to specific drives within the JBOD.The CLI offers a wide range of features for managing the SAS JBOD:
Device Access and Security:
setpass command allows users to set a new login password (up to eight ASCII characters).lo command logs the user out of the CLI.System Identification and Status:
nickname command allows displaying or changing the device's nickname, aiding in identification in multi-device environments.systeminfo command provides a quick overview of the JBOD's hardware and firmware versions.system status command monitors critical temperatures (chip and ENC), which is vital for preventing overheating and ensuring system stability.sasaddr command helps in identifying the unique SAS addresses of the expander ports.Physical Layer Management:
rtr command displays the default route and routes for specific destination addresses, with options to show enabled, disabled, or all routes. This is useful for understanding how data is routed within the SAS fabric.phyinfo command provides detailed information about physical layers, including power management, connected layers, cable management, and EDFB (Enhanced Drive Failure Bypass) status. It can also display information for specific physical layer numbers.link command allows administrators to manually set the maximum and minimum link speeds for individual physical layers, optimizing performance or compatibility with connected devices.Device Control:
fan command allows displaying the current fan speed status and setting the fan speed to automatic (auto) or a specific level (1-7). This is important for thermal management and noise control.edfb command enables or disables EDFB, a feature that can enhance drive reliability by bypassing failed drives.locate command helps in physically identifying a disk by its position, which is crucial for maintenance tasks like drive replacement.buzzer command enables or disables the system buzzer, useful for silencing audible alerts during maintenance or in quiet environments.Zoning Configuration:
phyzone command is a powerful tool for configuring storage zones. It allows users to:
on/off).default).get).clr <group number>) or all zone settings (clr all).<group number> <start slot> <end slot> <SAS port>). This enables granular control over which hosts can access which drives, enhancing security and resource allocation.System Reset:
reset command performs a reset of the device. It's noted that after a reset, the device password must be re-entered. This command can be used for troubleshooting or applying certain configuration changes that require a system restart.The CLI provides several features that are directly relevant to system maintenance and troubleshooting:
system status: Regularly checking chip and ENC temperatures helps in proactive thermal management and prevents hardware failures due to overheating.counters: Monitoring physical layer error counters (InvWrdCnt, DispErrCnt, LossSyncCnt, RstSeqFailCnt) allows administrators to detect and diagnose issues with SAS links, such as cable problems or faulty ports, before they lead to data loss or performance degradation.phyinfo: Provides detailed insights into the status of physical layers, including cable management information, which can help in identifying issues related to cable connections.rtr: Examining the route table can help diagnose connectivity problems within the SAS fabric.sasaddr: Verifying SAS addresses ensures that all connected ports are correctly identified and functioning.locate <disk number>: This command is invaluable for physically locating a specific drive within the enclosure, simplifying the process of replacing faulty drives or performing other hardware maintenance.edfb: Enabling or disabling EDFB can be part of a maintenance strategy to manage drive failures and maintain system uptime.buzzer: The ability to enable or disable the buzzer allows administrators to control audible alerts, which can be useful during maintenance periods to avoid unnecessary noise or to ensure critical alerts are heard.systeminfo output includes "Enclosure FW V", suggesting that firmware updates are a part of the device's lifecycle, likely managed through a separate process or a more advanced CLI command not fully elaborated in the provided snippets.reset command can be used as a last resort for troubleshooting or to apply certain system-level changes, effectively restarting the SAS expander.In summary, the QNAP SAS JBOD CLI 1.0 offers a robust set of commands for in-depth configuration, monitoring, and maintenance of the SAS JBOD enclosures, catering to users who require fine-grained control over their storage infrastructure.
