Release Notes for Sun Storage 6580 and 6780 Arrays 15

Installation and Hardware Related Issues

This section describes known issues and bugs related to installing and initially

configuring Sun Storage 6580 and 6780 Arrays.

Single Path Data Connections

In a single path data connection, a group of heterogeneous servers is connected to an

array through a single connection. Although this connection is technically possible,

there is no redundancy, and a connection failure will result in loss of access to the

array.

Caution – Because of the single point of failure, single path data connections are not

recommended.

Setting the Tray Link Rate

When setting the tray link rate for an expansion tray, all expansion trays connected

to the same drive channel must be set to operate at the same data transfer rate

(speed).

For details about how to set the tray link rate, see “Setting the Tray Link Rate” in the

Hardware Installation Guide for Sun Storage 6580 and 6780 Arrays .

Upgrading the Sun StorageTek 6540 Array

Bug CR 6783749 – When upgrading a Sun StorageTek 6540 array to a Sun Storage

6580 or 6780 Array, you cannot change the tray ID 85 to tray ID 99 using CAM.

Workaround – You can use controller tray ID 85 for array configurations up to a

maximum of 256 drives.
