2-8 Sun StorEdge A1000 and A3x00/A3500FC Best Practices Guide • November 2002
Note – Refer to Escalation no. 525788, bug 4334761. Refer to FIN I0612 for further
information.
Caution – If the drives you are adding to the array were previously owned by
another controller module, either A1000 or A3x00/A3500FC, ensure that you pre-
format the disk drives to wipe clean the old DacStore information before inserting
them in an A3x00/A3500FC disk tray.
Caution – Do not randomly swap drives between drive slots or RAID systems. You
must use the Recovery Guru procedure to replace drives. Also see Section 5.2.10,
“Disk Drives” on page 5-14.
Caution – If you take out a disk drive, put a dummy drive in so proper cooling can
be maintained.
2.4 Setting Up 2x7 and 3x15 Configurations,
and Converting 1x5 to 2x7 or 3x15
To connect the power and SCSI cables to the new disk tray, and to set the disk tray
ID (and the option switch on D1000 trays), refer to the Sun StorEdge A3500/A3500FC
Hardware Configuration Guide.
Because of the re-cabling, the drive DacStore will be erroneous. Some drives might
fail or not appear. Ghost drives might appear. Do not attempt to fix these problems.
You first need to delete all previous LUN configurations. A Reset Configuration may
work, but the best thing to do is issue a sysWipe command then sysReboot on
each controller through the serial port.
Caution – Only trained and experienced Sun personnel should access the serial
port. You should have a copy of the latest Debug Guide. There are certain commands
that can destroy customer data or configuration information. No warning messages
appear if a potentially damaging command has been executed.
