Your machines won't come up running, they'll start up from scratch (like if you
had hit the reset button).
If you want your machines to come up you have to make vmware snapshots, which
capture the state of the running VM (memory, etc..). Typically this is
automated with solutions like VCB (Vmwa
Thanks for your answer.
I asked primarily because of the mpt timeout issues I saw on the list.
I never experienced timeouts with my (personal) usas-l8i (lsi 1068e) but feared
this issue might cause some problems with 3081.
Anyway, thanks again.

Has anyone worked with a x4500/x4540 and know if the internal raid controllers
have a bbu? I'm concern that we won't be able to turn off the write-cache on
the internal hds and SSDs to prevent data corruption in case of a power failure.

Hi,
I have a mysql instance which if I point more load towards it it suddenly gets
100% in SYS as shown below. It can work fine for an hour but eventually it gets
to a jump from 5-15% of CPU utilization to 100% in SYS as show in mpstat output

I'm working with a Cyrus IMAP server running on a T2000 box under
Solaris 10 10/09 with current patches. Mailboxes reside on six ZFS
filesystems, each containing about 200 gigabytes of data. These are
part of a single zpool built on four Iscsi devices from our Netapp
filer.

Hi--
The best approach is to correct the issues that are causing these
problems in the first place. The fmdump -eV commnand will identify
the hardware problems that caused the checksum errors and the corrupted

You might be able to use some combination of zpool scrub, zpool clear,

Hi Dan,
I'm not sure I'm following everything here but I will try:
1. How do you offline a zvol? Can you show your syntax?
You can only offline a redundant pool component, such as a file, slice,
or whole disk.
2. What component does "black" represent? Only a pool can be exported.
3. In genera
Dan,
I see now how you might have created this config.
I tried to reproduce this issue by creating a separate pool on another
disk and a volume to attach to my root pool, but my system panics when

This is on Nevada, build 130.

I've got auto-snapshots enabled in global zone for home directories of all

Hi,
I think you are saying that you copied the data on this system from a
previous system with hardware problems. It looks like the data that was
copied was corrupt, which is causing the permanent errors on the new
system (?)

"(Caching isn't the problem; ordering is.)"
Weird I was reading about a problem where using SSDs (intel x25-e) if the power
goes out and the data in cache is not flushed, you would have loss of data.
Could you elaborate on "ordering"?

"Yes, write cache is enabled by default, depending on the pool configuration."
Is it enabled for a striped (mirrored configuration) zpool? I'm asking because
