I am in the process of cleaning out the lower cabinet of an HSZ70 array
controller. Here is the output from /sbin/scu:

I accessed the lower cabinet via hsxterm:
/usr/lbin/hsxterm b5 t0 l0
which, if I understand correctly, placed me on the upper controller of the
lower cabinet.
The first device I wanted to delete was D0. According to the documentation,
I need to clear lost data errors or unwriteable data before deleting the
unit. So here are the commands I ran and the output:
Lower-Upper> clear_errors d0 lost_data
Error 7060: Cannot clear LOST_DATA on a unit without LOST_DATA
OK. I figured that perhaps LOST_DATA was a parameter not defined when the
unit was created.
Lower-Upper> clear_errors d0 unwriteable_data
Error 7070: Cannot clear UNWRITEABLE_DATA on a unit without
UNWRITEABLE_DATA
Same conclusion. So then I performed the delete:
Lower-Upper> delete d0
ScsiExecCli Failed
It sat like this for several minutes, and when I pressed the RETURN key the
message repeated. Finally, I entered <ctrl-C> which bounced me out to the
shell prompt. But now when I try to re-enter on bus 5/target 0, I receive
the following message:
Unable to open device
Previously, I could still access the lower cabinet from the lower controller
(bus5/target 1). However, not that appears to not be working.
I need answers to the following questions:
* The StorageWorks documentation stated that I should clear errors before
deleting a unit. Is that always necessary?
* What is the meaning of the message ³ScsiExecCli Failed² and what do I do
to avoid it?
* What do I need to do to clear the controllers on the lower cabinet (bus 5)
so I can access it via target 0 or target 1?
Thanks for your help,
-Ric
