Select the drive you want and press Enter.
If the TUR was successful, TUR STATUS OK displays.
If the TUR was not successful, a failure message displays.

Press Esc to return to the Drive Utilities Menu.
Managing SAF-TE Enclosures
A SEP (SAF-TE Environmental Processor) is a SCSI device from which the RAID
controller can inquire about environmental conditions such as temperature, power
supply and fan status, and the presence or absence of disk drives. The RAID
controller can also tell the SEP about RAID activities such as drive rebuilds and failed
disk drives.
SAF-TE configuration settings are automatically enabled when G- and K-Series
controllers are installed in an enclosure that contains a SEP. No changes are required
to the default configuration settings to support SAF-TE.
You can control the following functions for SEP enclosures:
!
Change the SEP LUN (see page 8-12)
!
Change additional SEP settings (see page 8-14):
– Polling interval
– Temperature sensor status
