Drive

Electronic serial number of the drive. *NO-SERIAL* indicates it is not known.

Note – This field links to the Drives – Overview screen, detail view, which displays all available details for this drive. See “Drives Overview and Analysis Screens”.

Drive WWNN

World Wide Node Name for the drive slot.

Drive Type

Drive type long description sent by the library. For example, T10000c‑Enc, HpUltrium4, etc. UNKNOWN indicates a broken drive or a drive for which STA cannot determine the type.

Note – Type is UNKNOWN for all DLT and SDLT drives, for which STA does not compute health.

Drive Health Indicator

Drive health. This is a point-in-time value computed by STA analytics based on data gathered from the drive during current and past exchanges. It reflects a variety of factors, such as the drive’s error history, read margin, and write efficiency.

This value includes all data up to and including the last completed exchange. It is updated immediately after each completed exchange involving the drive.

Possible values, in order of degrading health:

•	USE – The drive has had no failures or degradation in the last ten exchanges.

•	MONITOR – The drive has had multiple errors; there is a less than 80 percent chance that it needs service.

•	EVALUATE – The drive has had multiple errors; there is a greater than 80 percent chance that it needs service.

•	ACTION – The drive has had an error that requires attention. The drive may require service. You should investigate and determine a proper course of action.

•	UNKNOWN – STA has not received enough data to compute health for the drive. This may be due to a variety of factors, including an unsupported drive model, downlevel drive firmware, or ADI mode not enabled for an LTO drive.

Note – STA only receives information about errors detected by a drive while performing read/write activity to a cartridge. STA does not receive information about errors that may occur in the data path or the host application.

Note – Cleaning exchanges have a neutral impact on drive health.

Last Drive Notification

Health of the library drive control path. Updated whenever notifications for the drive are received by STA from the library. Possible values:

•	DEGRADED – The drive is offline. Also may indicate the drive is in need of cleaning (applies only to SL3000 and SL8500 libraries with the drive cleaning warning set to “on”).

•	NORMAL – The drive is functioning normally.

•	NOTOPERATIVE – The library has lost communication with the drive, or the drive has experienced an error or mechanical failure.

•	UNKNOWN – STA has not received any notifications for the drive. This is the default value until the first notification is received for the drive.

Drive ID

Library drive bay where the drive is located.

Drive WWPN (Port A)

World Wide Port Name for drive port A. This is automatically generated by the library controller during library initialization.

Drive WWPN (Port B)

World Wide Port Name for drive port B. This is automatically generated by the library controller during library initialization.

Drive Model

Drive model short description. For example, T10000C, LTO4, etc. UNKNOWN indicates a broken drive or a drive for which STA cannot determine the type.

Note – Type is UNKNOWN for all DLT and SDLT drives, for which STA does not compute health.

Drive Manufacturer

Drive manufacturer.

For example, STK, IBM, QUANTUM, etc.

Encryption Capable

Indicates whether the drive is capable of supporting encryption, but does not necessarily indicate that encryption has been enabled. Possible values are Yes or No.

Note – Additional hardware or software components may be necessary to actually enable encryption on the drive. For example HP LTO4 drives require a Deoni card and IBM LTO4 drives require a Belisarius card.

Drive Interface

Host interface type for the drive. Possible values:

•	SAS – Serial Attached SCSI

•	SCSI – Small Computer System Interface

•	FIBRE – Fibre channel

•	UNKNOWN – The library did not report the interface type.

Drive Properties Updated

Date and time when the drive properties were last updated. Initially set to the date and time when STA first recognized the drive, and updated whenever subsequent updates occur, such as updating the drive firmware.

Drive Firmware Version

Drive firmware and host interface level. See the STA Planning and Installation Guide for details on whether this firmware version supports rich data for STA.

STA Start Tracking

Date and time when STA first began tracking this drive serial number.

STA Stop Tracking

Date and time when STA stopped tracking this drive serial number. This is when STA determined the drive serial number no longer exists in any of the monitored libraries and updated the drive status from “missing” to “removed”.
