Hi,
I have a system with multiple file system created under SVM. The server
is connected to D1000 disk array. I had a short power failure (over 20
seconds). One power supply on D1000 is connected to clean power, second
power supply to dirty power.
D34 / D33 mirror is giving me Needs maintenance / Last Erred messages.
I was able to resolve the problems with the internal disks mirror drives
but the RAID 10 can not too good info on SUN website.
What is the best approach to resolve the mirror problems?
I will summarize. Thank you, Pawel
SunOS xxxxxxx 5.9 Generic_117171-08 sun4u sparc SUNW,Ultra-80

Subject: Offtopic: Storage System Comparison
Hi,
Firstly sorry for this offtopic question.
I am in a process of evaluating different storage system for setting up
our enterprise SAN and would like to have your feedback and would like
you
to share your experience on the same. The Storage systems we are looking
in for are namely EMC's CX700 / DMX 1000 or HDS Thunder 9585V or USP100
(equivalent to HP XP12000 series of boxes). I would request you to share
your opinions and experiences about the technology and the support that
these vendor offer.
Thanx in Advance.
Regds,
- Rajan
