Sun StorageTek 6140 Array Release Notes, Release 6.2 29
Workaround - To avoid having the array incorrectly initiate a volume migration
process with the newly introduced replacement drives, perform one of the following
tasks:
■
Verify that the volume on the Sun StorageTek 6140 Array with the failed disk
drives has not been deleted. You should leave the volume in a failed state and not
delete the volume.
■
Verify that the disk drives being taken from the inactive Sun StorageTek 6140
Array are not part of an active volume. If the disk drives are part of an active
virtual disk, delete all volumes residing on that virtual disk before removing the
disk drives.
Controller Tray ID Numbering Is Unrestricted
Controller tray IDs can be set to any number between 0 and 99. Expansion trays use
the values 0 to 79. Controller trays should use the values 80 to 99 (except 85) to
avoid duplicate tray IDs.
If tray IDs are duplicated, the array will not be able to detect the drives on one of the
two trays that have the same ID (which one is arbitrary). Do not use ID 85 for the
controller tray, as this number is the default setting that indicates everything is
operating as expected.
The Expansion Module Must Be Set to the Same Speed As the Controller
The controller and expansion modules must be set to the same speed. If the 2/4GB
switch is set to 2GB on one and it is set to 4GB on the other, the expansion module
will appear inoperative with no indication of the cause.
The controller is set to 2GB at the factory. An expansion module is set at the factory
to whatever its disk drives are. You can tell what the speed of the disks on the tray
are by removing one of the disks and examining the label. Next to the disk name on
the label there is a number indicating the RPM and speed of the disk. For example,
the number 15k.4 indicates the disk is 15,000 RPMs and 4GB.
Cable Adapters
The array ships with two RJ-45 to miniDIN cables, a RJ45-DB9 adapter, and a RJ45-
DB9 adapter with a null modem. The two adapters allow users to connect to the
array from most Sun workstations, portable PCs, and terminal servers. If your ship
kit does not include the RJ45-DB9 adapter with a null modem and you cannot
connect with the RJ45-DB9 adapter, either supply your own adapter or contact Sun
Service.
