Hi Guys,

Is there anyway I can issue an

./ipmitool mc reset cold

from the extended console or the like within open-e DSS V6.

My primary has dropped it's IPMI connection and a reboot...

Hi,

No CacheCade,

The firmware is 2.120.53-1235

Do I have to be concerned with possible data loss enabling the Disk Cache? or is that negligible in my setup? BBU + Duel power supplies + A+B...

I had just upgraded to the latest version of DSS today.

I can't seem to connect to the LSI controller via the MegaRAID Storage manager, is there a setting I need to enable in DSS to allow the...

My RAID cards are

Hi All,

Help, I'm seem to have an issue withe my DSS Setup.

Since upgrading to ESXi 5.0.0 I've had nothing but issues with I/O.

Hi guys,

I have 2 DSS V6 machines in an Active/Passive Setup I wish to change the main IP I access the DSS on, BUT I really can't afford the downtime of pulling my whole VM environment (80+ VM's)...

Hi Toni,

How did you go with your method in production?
Have you done it? and if so did it work?

Cheers

Alliance,

Give us the run down on your hardware/mainboard/disk drives.
I was having much the same issues with the 3ware card as you.

I discovered incompatibility with the 3ware card mainboard...

But that means downtime, and if it is pooched a dead DSS machine.
Is there a way via the GUI or via console.
I think my secondary node has a USB stick that is dead/dying, but there isn't any...

Hi all,

Just a quick question, both my DSS V6 SANS boot off USB sticks. I was wondering how can I run a "test" of the USB stick to ensure it's ok, my SANS have been online for almost a year now...

I've have had a lot of issues with the 9650SE range of cards.

Intermittent dropping the card from the machines (the card completely disappears), very weird reporting on disk spindle speed's...

Thanks Al,

That is awesome background and great response :) Just what I was after.

Just an update, I in fact did failover to my secondary node, update the iSCSI settings on my primary node, re...

I have looked over the ESXi configuration the only settings NOT listed are these 2

Maxxmitdatasegment=262144
Wthreads=8

Does anyone know where/how to set them in ESXi 4.1?

Cheers

Hi All,

Reading the forums and the like this seems to be the "best fit" settings for iSCSI tuning.

headerDigest=None
DataDigest=None
maxoutstandingr2t=8
FirstBurstLength=65536...

Hmm I don't get this when I failover, ESXi 4.1 MPIO (4 nics), I can failover/back without any of the VM's rebooting or LUN timeouts etc. It works very well. I might get 1 dropped PATH on ESXi but by...

Anyone?
I don't want to have to down all my VM's to setup failover, is there a way this can be done?

I have a simple question, but it might be hard to explain.

I have 2 SANS's setup, identical spec.

The primary has been online for sometime with no failover config, but I had configured the LV's...

So is that a Yes I will have a problem? or a No I should be fine?
I DO have volume replication in place and is configured, but I haven't done the iSCSI failover yet.

Cheers
Adam

So even though I've already setup volume replication and it has synced (iscsi vol rep) I should still be able to change the hostname of my primary and it won't effect the volume (drbd) side of...

Ahh I like this idea as well, our sans are internal only etc, nice "idea" but the option to turn it off would be very good, I always assume something is wrong if I login and see that icon flash. ;o)...

Hi guys,

At what point can I change the "hostname" on my DSS machine without causing any issues.

I setup my primary SAN and completed the setup of the volume replication and just synced all my...

I've never liked the idea of a hot spare, I've lost a 4TB raid to the gods thanks to a hot spare and auto rebuild.

Open-E cover off the reason's why... worth a read.

Hi guys,

I've run into a bit of an issue, I'm just not sure how to do this.
As I stated my VIP's are
eth0 10.1.5.100
eth1 10.1.6.100
eth2 10.1.7.100
eth3 10.1.8.100

Which are only active...

ugh that won't work actually, all the switches are in the same subnet 202.xxx.xxx.xxx

how do I go about picking my ping nodes then?

I'm think switch01 and switch02 in the 202 subnet, but how do...

Excellent, now I get it...

BUT..

You can indicate up to 10 ping nodes. Please use comma as the delimiter (e.g. 192.168.0.1;192.168.0.2 etc.). Automatic failover will only take place if all...
