Using the Sun StorEdge T3 Array with VxVM

Using a T3+ as a Boot Device

To use a T3 as a boot device, the T3 needs to satisfy some requirements:

1. All T3 firmware should be at level version 2.1 or higher. To confirm that the T3

firmware is at the necessary level, log on to the T3+ and enter the command:

# t3plus:/:<1>ver

and you should see output similar to the following:

T3B Release 2.01.00 2002/03/22

2. The volslice parameter should be in a disabled state. Log on to the device and enter the

command:

# t3plus:/:<1>sys list

you will see output, similar to the following, that includes a reference to the

enable_volslice:

enable_volslice : on

If volslice is set to on, you cannot boot from the T3+ device.

The T3+ device should be directly connected to the machine, and no switch should be

involved. If you are connecting through a switch, then you need to refer to the Solaris

Operating system and T3+ documentation for booting requirements.

T3B firmware upgrade Considerations

For the rolling upgrade to work, you need to break the mirrors and remove the disks from

the disk group. The upgrade can then be carried out on any array that is not in VM. The

disks are then added back to the disk group and the mirrors re-attached. This requires

that the mirrors are resynchronized, as in any mirror detach plex.

The following scenario shows how to upgrade T3B firmware from 2.0 to 2.1.

Note It is required that a volume has one plex on each T3 unit. If the volume is not

mirrored across T3 units, please contact your hardware vendor.

1. Identify the volume which is on the T3B which you are going to upgrade the

Firmware. For example:

# vxprint -ht

dg new-dg default default 129000
