You can use the environment, fcadmin, sasadmin, storage show, and sysconfig commands to view information about your storage subsystems.
| Use this Data ONTAP command... | To display information about... |
|---|---|
| environment shelf | Environmental information for each host adapter, including SES configuration, SES path. |
| environment shelf_log | Shelf-specific module log file information, for shelves that support this feature. Log information is sent to the /etc/log/shelflog directory and included as an attachment on AutoSupport reports. |
| fcadmin device_map | What disks are on each loop and shelf. |
| sasadmin expander | What disks are attached to expander PHYs. |
| sasadmin expander_phy_state | Expander PHY state, dongle state and event counters, PHY statistics. |
| sasadmin shelf [short] | The disks on each shelf (or a specific disk shelf), including a pictorial representation of disk placement (long or short view). |
| storage show | All disks and host adapters on the system. |
| storage show adapter | FC host adapter attributes, including (as appropriate for the adapter type) a description, firmware revision level, Peripheral Component Interconnect (PCI) bus width, PCI clock speed, FC node name, cacheline size, FC packet size, link data rate, static random access memory (SRAM) parity, state, in use, redundant. |
| storage show disk -p | How many paths are available to each disk. |
| storage show expander | SAS expander attributes, including shelf name, channel, module, shelf ID, shelf UID, IOM state, and the following information for the disks attached to the expander: disk ID, port state, partial path timeout, link rate, invalid word count, running disparity count, PHY reset problem, CRC error count, and PHY change count. |
| storage show hub | Hub attributes: hub name, channel, loop, shelf ID, shelf user ID (UID), term switch, shelf state, ESH state, and hub activity for each disk ID: loop up count, invalid cyclic redundancy check (CRC) count, invalid word count, clock delta, insert count, stall count, util. |
| storage show mc | All media changer devices that are installed in the system. |
| storage show port | Switch ports connected to the system. |
| storage show switch | Switches connected to the system. |
| storage show tape | All tape drive devices attached to the system. |
| storage show tape supported [-v] | All tape drives supported. With -v, information about density and compressions settings is also displayed. |
| storage stats tape | Statistics for all tape drives attached to the system. |
| sysconfig -A | All sysconfig reports, including configuration errors, disk drives, media changers, RAID details, tape devices, and aggregates. |
| sysconfig -m | Tape libraries. |
| sysconfig -t | Tape drives. |
