As one of the disks failed in the T3, suppose we are going to replace
it. If the new disk firmware is not the same as other disks(As the T3
is 4 years old), does it necessay to upgrade all other disks firmware?
If this is the case, then each time when replacing a new disk(new disk
always comes with new firmware), then we have to upgrade other disks
again. Please advice! Thanks

Hey,

lets take a look in the SUN handbook:

 The latest firmware for StorEdge T3 and T3+ Arrays and disk drives is
available in patches 109115-xx and 115180-03 or later. It is
recommended that these arrays and disk drives be updated with the
latest firmware.

I think you it's better to update your firmware.

Good Luck
