I've received several answers. Most of them suggested scsiinfo utility.
One can get it from ftp://ftp.cdf.toronto.edu/pub/scsiinfo. There are source
and binaries for all versions of Solaris.
I've downloaded and run scsiinfo utility and got answer to my question.
The utility showed all neccessary information about scsi devices.
There is standard method of displaying scsi drive information without
using third-party software. Use prtconf utility.
Here is piece of prtconf -v output from UE450:
[...]
scsi, instance #4
Driver software properties:
name <target2-TQ> length <4>
value <0x00000001>.
name <target2-wide> length <4>
value <0x00000001>.
name <target2-sync-speed> length <4>
value <0x00009c40>.
[...]
Here you can see three values for target 2: TQ, wide and sync-speed.
TQ is TaggedQueuing, wide - wide operation, sync-speed - is synchronous
speed.
The speed is <0x00009c40> KB/s - 40000 KB/s.
Here is piece of prtconf -v output from UE3000:
[...]
SUNW,isptwo, instance #0
Driver software properties:
name <target5-wide> length <0> -- <no value>.
name <target5-TQ> length <0> -- <no value>.
name <target5-sync-speed> length <4>
value <0x0000aaaa>.
[...]
The speed is <0x0000aaaa> KB/s - 43690 KB/s.
