But how to update to latest release and then reactivate DSSv7.0up75, if activation service doesn't work any more? Will go with manual activation?

One of standalone SSD drives has broken and after restart this node without that SSD, strange notice apeaded, that this node is not activated any more...

What about "Maintenance Mode", can I use "stop and enable VIPs" option and move to a-a?

All current sources/destinations are stay unchanged.

I've created new unused replication task, not used...

Hi!
Is there any faster procedure as http://kb.open-e.com/How-to-move-from-Active-Passive-to-Active-Active-mode_1843.html
Without stopping failover?

Solved!

Looks like this problem apears, if ADS server IPs on both servers are not equal?!?

Is it possible to run iSCSI and NFS replication tasks together?

I want to add a replicated NFS task to my system but this error apears:

This 5 year warranty is unfortunate limited with Wearout indicator (or Endurance Rating for easier calculation).

When SSD is used in CacheCade, data is written on it when we write into Datastore...

Yes, for each node I use 2 Samsung SSDs 850 Pro 512GB in RAID1.
512GB is also the largest CachaCade capacity :confused:.

For past 527 days (with 100,0% active cluster!) I used 2 Intel S3500...

I intend to replace the old disks to the passive node. When full volume replication will start again (about 8TB), I see no reason, to enable SSD Cache on both nodes - just increase wearout of SSD and...

It's first time for me too!
As I explained before, the Drive Group expansion is only possible with single Virtual Disk.

I noticed some small print on support page:

NOTE: ...

We can add additional iSCSI target without breaking cluster – and this is good!

This is the point of my question:

Is it recomended to adjust target settings to initiator defaults?

Default iSCSI settings are different between VMWare, Server2008 and DSS7
(can't find...

I'm interesting for explanation, too:)

...not to open new thread:

We are planning to combine two separate DSS7 iSCSI targets:
- one for VMWare ESXi initiators with parameters (recomended above)
maxRecvDataSegmentLen=262144
...

For now, we use 2 TrendNet TEG-448WS for connect 2 DSS, 3 VM Hosts (together 12 1GbE potrs for iSCSI) and also many other equipment and it works quite fast - low budget and it works.

Maybe, my...

Ah, yes, I see now.
Thank you for fast answer.

If we have more than 1 array, does the primary node failover on IO errors of ANY array?

Restore default network settings (IP, BONDING) was helpful for me, once upon a time.

Noticed on our ESXi 5.0 hosts:

I try to enter iSCSI targets by type VirtualIP on Dynamic Discovery, first.
After rescan process, there are list of all discovered targets on Static Discovery tab....

Now, I'm back from winter hollidays and I'm planning to realize "my" method in real word.
(never start tasks like this before hollidays, if you don't want to ruin them)....

....month or two...

I've just tested a little different scenario.

After power off both serveres, I've switched on Secondary first.

In this case, VIP is not active until we:
- change Volume replication modes to...

I can't!

But you can look into log file (Status/HW/Download...) and use some common logic - not 100%, but it helps to sompose an image.

Maybe, you can't, because address is already reserved for VIP (failover/ifaces.conf).
Anyway, you'll have problems later, to start Failover again.


Can you use multipath on iSCSI client?
