3.4.4
Adding disk drives
• Built-in disk drive bay of main unit
The PRIMEPOWER850 rack-mount type (16U) server can accommodate up to four
built-in, hot swappable Ultra SCSI disk drives. Each disk drive bay is provided with
an ACCESS LED and an “Insertion/extraction” LED.
The ACCESS LED lamp lights in green when the disk drive unit is operating (reading
or writing). The “Insertion/extraction” LED lights based on the swapping procedure
during hot swapping.
• Hot swapping the disk drives
4
Users must use disk mirroring software to mirror the hard disk drives before the
hot swapping feature can be used. The disk mirroring software
“PRIMECLUSTER GDS” is available from Fujitsu/Fujitsu Siemens Computers.
The disk drive units installed in the main unit can be hot swapped. To execute hot
swapping, monitor the ACCESS LED and “Insertion/extraction” LED by using the
machine administration tool included in the Enhanced Support Facility.
For a description of the swapping procedure, refer to the Machine Administration
Guide supplied with the Enhanced Support Facility.
Data destruction
Contact a certified service engineer if a hard disk drive must be hot swapped.
Data may be lost if the hot swap procedure is not performed correctly.
