Questions:

tip or telnet - but what about ssh?  (It turned out that telnet and
serial were both possible, as were running commands on the host  system -
the V440 in our case
/\/\/\/\/\/\/\/\
Did we get the redundant controller option?  Yes, two controllers
according to pdf
/\/\/\/\/\/\/\/\
2T lun limit still?  Must LVM (conacatenation/RAID 0 with SVM, or maybe
QFS will do this)?  Is it preinstalled with Solaris 10 update 2?  I don't
see anything about update 1 being available yet in about 30 minutes of
googling (DRS)
"Solaris 9 Update 4 and later (including Solaris 10)
supports filesystems greater than 2 TB, but the LUN is still limited to
2 TB."
"This is due to sd (SCSI driver) only using SBC-2 SCSI commands which is
limited to 32-bits addressing of blocks at the raw device level."
Jun 23 2005 "This limitation is scheduled to be removed in an upcoming
Solaris 10
Update 2."
"You can still use SVM or VxVM to concatenate multiple LUNs to present a
single metadevice/volume for filesystem creation."
"This system administration enhancement is new in the Solaris Express
6/05 release."
"Your problem is most likely due to the sd.conf file setting and the
capacity beyond 2TB per LUN Per SCSI ID#.
Please make sure that your sd.conf file offers enough number of LUNs
and SCSI ID# as well as try to cut the LUNs to less than 2TB.
Please note although that Sun allows the over 2TB capacity, but you
may have limitation at the SCSI controller level. Please check your
SCSI adapter configuration and ask the vendor to verify beyond 2TB per
SCSI ID#."
"try a 'format -e'.
Than you could select the EFI Label. Maybe that works."
"I found a Sun document outlining the problem. Document ID: 80032 states
that the limitation is that the SCSI driver currently does not support
SBC-2 commands and therefore have only a 32-bit logical address block
field - with a block being 512bytes, that makes a maximum addressable
scsi device of 2TB (2^^32 x 512 bytes).
The document also says that the 2TB scsi device size limitation is
scheduled to be lifted beginning with Solaris 10, Update 2. Releases
earlier than that still have the 2TB limitation.
My only question now is: when is Solaris 10, Update 2 due out?"

Note - Do not use a Sun StorEdge 3511 SATA array to store single
instances of data. It is more suitable for use in multipath and multi-host
configurations where the array has a backup or archival role.

The ESMF DDSS 3511+QFS has been set up and in production for a while now.
Today, I'm just documenting what disks are being put to what uses.

1-11 logical drive S0 (10 disk RAID 5)
11,17-25 logical drive S1 (10 disk RAID 5)
26-27,33-40 logical drive S2 (10 disk RAID 5)
41-43,49-55 logical drive S3 (10 disk RAID 5)
56-59 logical drive S4  (4 disk RAID 5)
0,16,32,48 global spares

Each of the four 10-disk RAID 5's are split into two LUN's, one of
1715818M, and one of 1715819M.
The single 4-disk RAID 5 is mapped to a single 1143879M LUN
