Mirror/Device issues

[Sandy Flint]

It appears that our backup software (ArcServeIT6.6) may be causing
mirror problems.

About once every 7-10 days, I get an abend or a mirror problem (always
occuring during the backup timeframe). Both of these issues also
increase redirected blocks (apparently by 1 block each time - but that's
not for certain.) (I have a total of 15 redirected blocks.)

My physical setup is this:
2 drives - duplexed on AHA2940 adapters.
Seagate Tape unit hangs off of one of the adapters along with one of the
drives.

I admit that I may have a host adapter problem, but all of my errors
come during backup time. And I don't get redirected blocks any other
time either.

My most recent issue looks like:

1:01:32 am unmirror of partition1

1:01:32 am Device Seagate ST1523ON 0252 deactivated by driver due to
device failure

1:01:32 am Volume SYS still operational despite drive deactivation

1:01:41 am Device #17 AIC-7870 Host adapter has been deactivated.

1:01:41 am Host Adapter not responding to abort.

I'm currently trying to get a new host adapter in house, but that's
going to take a couple of days.

Any other suggestions?

TIA

Hallo,

may be You have the same problem as I, see the message chain about
Novell-Netware 3.2 with Adaptec 2940 AU (duplexing/mirroring) above.

Sandy,
one important issue - it is BAD NEWS to put the tape unit on the same
controller as the disks - causes all sorts of issues...

Shaun,

so if you want to have a duplexed system I guess you need Three Scsi
controllers. Add video and two nics (to segment the ethernet) and your out
of slots?

Hi Pat,

I use ISA video so as to free up a PCI slot. <G>

Pat,
that's why they make systems as SERVERS - often with onboard video, and
one or 2 scsi controllers, ethernet, and another 6 slots...

Or alternatively, give up on duplexing and go with RAID instead, eh?

Pat,
I reckon I've bought around 300 over the years...

Right, you just don't get the performance improvement out of RAID...

Oh, you want performance and reliability, then duplex the RAID -- $$$$$

Well, there is that.

I'm still using 340 MB IDE! <G>

Yup, might even have a REAL large 1.2G drive around.

Pat,
none had been perfect, but i guess that Dell have caused me fewest
headaches...

[Felton Green]

Hi Barry,

I've found that laptop drives ( in abundance around here) work well ( I've
lots of 300 MB drives because of the small size )

Hi Don,

So, when you come up with a spare 500 MHz system with 20 or so GB on it and
maybe 256 MB of RAM you want to give away, let me know! <G>

Let's see, what's that John Denver song?

o/~o/~

It's been too long! Lots to do in Toledo -- sit in the park and watch the
grass grow, stand in front of the bakery and watch the buns rise. Toledo! The
folks who gave us "No springs, honest weight!" That was the jist of the song.

[Barry Schnur]

Well, first off I need to get a spare car battery for your son <smile>

[Felton Green]

Hi Don,

LOL... yes it's true the sidewalks roll up at 8pm

He missed a meeting he was scheduled for at a client (we share this client), because he
was 'sans working car/truck battery'. Last we heard, he was walking the mile to the parts
store....

Glad I didn't hear about it! It usually takes at least half an hour... then we can get
down to business. But, that's not fun this time of year.

[Barry Schnur]

Right -- he ended up on a conference call instead, said he'd get the battery taken care,
but before showing up on site later in the day, he'd take at least one shower <g>

FYI, I used to get the same error messages on both of my Adaptec based
servers. My Always (IN-2000) based server never deactivated a drive or
controller, it just died when ever ARCserve 5 or 6 ran. The fix was to
find a 5 user NetWare license and put it on an independant tape server.
That combined with DLT drives fixed everything! Now if the tape server
has a nervous breakdown (aka ARCserve fit), I can punch the big red
button without the users being affected. IMO, running ARCserve on a
file server is just asking for trouble.

Don,
I have (had) around 60-70 servers running arcserve, with no problems to
speak of.
