Installing and Removing System Components

The following table shows SCSI drive status LED descriptions.

SCSI Drive
Present, Power On

Green LED

SCSI Drive
Active

Green LED

SCSI Drive
Faulty*

Yellow LED

Description and Action If Needed

On

Off

Off

Drive is present with power.

On

Blinking

Off

Drive is present with power and is being accessed.

Off

Off

On

Drive CAN be replaced. Steady yellow fault light
indicates drive has a problem. Power to drive is off.

On

Off

Slow
blinking

Drive SHOULD NOT be replaced at this time. A slowly
blinking yellow fault light indicates a drive that has just
been replaced is in recovery mode (drive array being
rebuilt). Power to drive is on.

Off

Off

Off

There is no drive installed in the bay.

*  Table assumes a SCSI host controller is installed to send SAF-TE control signals to the drive fault

LED.

Note: The DIGITAL Server 9100 series utilizes a Fault Reporting mechanism called SAF-TE (SCSI
Accessed Fault Tolerant Enclosure) for reporting hot-swap disk drive activity and status.  All other
DIGITAL Servers as well as external Expansion Cabinets use the DIGITAL Fault-Bus for reporting of
hot-swap disk drive activity and status.  The Mylex RAID controllers provide support for both types of
fault reporting and are shipped configured for SAF-TE when factory installed or Digital Fault-Bus when
ordered as standalone options.  A RAID controller can be configured for SAF-TE or Fault-Bus but not
both.  Consequently, a RAID controller configuration with one channel connected to internal hot-swap
disk drives (SAF-TE) and another channel connected to an expansion cabinet (Fault-Bus) is not
supported.
