I've had a similar experience, see below. The last contributor suggested that the problem may not be caused by the hard disk itself, but rather by an external device. In my case all servers have a cd drive. Could it be that under certain circumstances a cd/dvd could trigger this error on the hard disk.
The 3 messages listed below are from /var/adm/messages at the time the T2000 server hung. The same error occured on several T2000 servers over a period of 6 weeks. The submirrors d16 and d17 of mirror d15 were in a state of needs maintenance. The slice 0 of one disk was somehow corrupt and a simple metareplace wasn't sufficient to bring the system back up.
I also would really like to find the route cause of this error

The servers have in the meantime been updated to the firmware listed below, also the problem has not reoccurred since then but I still dont know what lies behind the error.

cmdk(7D) Devices cmdk(7D)
NAME
cmdk - common disk driver
SYNOPSIS
cmdk@target, lun : [ partition | slice ]
DESCRIPTION
The cmdk device driver is a common interface to various disk devices. The driver supports magnetic fixed disks and magnetic removable
disks.
The cmdk device driver supports three different disk labels: fdisk partition table, Solaris x86 VTOC and EFI/GPT.
The block-files access the disk using the system's normal buffering mechanism and are read and written without regard to physical disk
records. There is also a "raw" interface that provides for direct transmission between the disk and the user's read or write buffer. A sin-
gle read or write call usually results in one I/O operation; raw I/O is therefore considerably more efficient when many bytes are transmit-
ted. The names of the block files are found in /dev/dsk. Raw file names are found in /dev/rdsk.
I/O requests to the magnetic disk must have an offset and transfer length that is a multiple of 512 bytes or the driver returns an EINVAL
error.
Slice 0 is normally used for the root file system on a disk, slice 1 as a paging area (for example, swap), and slice 2 for backing up the
entire fdisk partition for Solaris software. Other slices may be used for usr file systems or system reserved area.
The fdisk partition 0 is to access the entire disk and is generally used by the fdisk(1M) program.
