Hi Som,
My point of view, the problem could not caused by Synchronize_cache failure.
Because synchronize_cache is not a mandatory command in SCSI spec, that
means
even without the command, the system can work fine.
My guess there is some error on your handler for WRITE. In another
words, I guess
something wrong during your driver write buffer out.
Could u do a experiment as below:
1. boot the machine with Solaris CD and your ITU disk
2. using `bootadm update-archive -R $ROOT` to update the boot-archive on
your iSCSI target.
Here $ROOT should be your mount point of your alternative root.
3. before reboot, could you verify the new boot-archive under your
$ROOT/platform/i86pc/ corrupt or not.
4. if the image correct, please reboot the machine from your iSCSI
target again.
If #3 is failed, that means your write has some problem. So please do
test write and verify with your driver.
Cheers
Javen
I am attempting to do an iSCSI LUN boot using my iSCSI
HBA driver with the 8/10/07 Solaris CD. Able to feed
my driver using the ITU diskette with my driver
package succesfully, my driver gets detected ,LUN for
boot is made available for selection and the entire
installation for the selected distribution (tried many
options from entire to just 'reduced network support')
goes through 100% ,eventually the 'reboot' screen
prompt appearing .
I'm copy pasting
below
the first few lines of the install_log and also
the end of the file

On reboot, i get GRUB error saying 'Error 28:selected
item cannot fit into memory'
I was able to boot into the system back using CD and
my driver,mount the FS of my LUN and using gunzip
verified that my bootarchive is corrupt
One thing that i constantly get in my system log
through the installation is a warning msg from the
SCSI driver saying
scsi: SYNCHRONIZE CACHE COMMAND FAILED(5)
Couldnt find much help on this and if this is the
rootcause of the problem
BTW,i tried local install of the OS on a SCSI HD using
Adaptec SCSI HBA and it worked fine
PS: I have also tried installing with 'kd' enabled and
kmem_flags set to check kernel heap memory corruption
and nothing showed up
Pls advise
Thanks
Som
