Volume Serial Number

Volume serial number (VSN or volser) assigned to the media by its external label. If the library does not supply the volser, STA provides one composed of Library Serial Number:Physical Address.

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

Media Type

Media type short description. For example, LTO1, T10000B, etc. UNKNOWN indicates media with a missing or unreadable external volume serial number (VSN or volser) label.

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

Media Health Indicator

Media health. This is a point-in-time value computed by STA analytics. It reflects a variety of factors, such as the media’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 this media.

Possible values, in order of degrading health:

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

WORM/VolSafe Media

Indicates whether the media uses StorageTek VolSafe technology. STA does not know the status until the media has been mounted. Possible values: Yes or No. Blank indicates unknown.

Media Manufacturer Serial Number

Media serial number assigned by the manufacturer.

Note – STA does not have this information until the media has been mounted in a drive.

Media Manufacturer

Media manufacturer. Possible values are “STK” for StorageTek enterprise media, or “LTO” for LTO media.

Media Life Indicator

Indicates whether the media has reached the end of its expected useful life. Possible values: EOL, GOOD, UNKNOWN.

STA Start Tracking

Date and time when STA first began tracking this volume serial number (VSN or volser). If the volser is used on more than one cartridge, this field reflects the earliest start date available.

STA Stop Tracking

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