2 Xraids 1 Fiber Card

Hi,
I wonder if you can help, I have currently 2 Servers hosting 2 seperate Xraid systems. However im about to lose the one server. I am upgrading the one Xraid Lun with new Drives and i need to copy the data back on to the new LUN on the upgraded Raid from the other Raid, there is a stock shortage of Fiber Cards, otherwise i would have used an additional card, so is there anyway for me to Connect the 1 raid with the Data (1 Volume) to the server and the new Volume to copy the data over safely ? its another 3 weeks till another fiber card will arrive and getting a fiber switch for 1 transfer of data isnt an option.
Any Advice Please ?

The other missing part is how the arrays are configured.
With two XServe RAIDs, you actually have four separate controllers. In your current configuration this probably means two connected to Server A and two connected to Server B.
The question is how do the servers use their two arrays. If they're mirrored you could just break the mirror and mount one half on RAID 1 and one half of RAID 2 on the server to copy the data - you'd need to be careful when you rebuild the mirror, though.
If the RAIDs are striped, though, then you have a problem - you can't disconnect any of the RAIDs without losing data. In this case your only option is a second fiber channel card or a fiber channel switch so that you can connect both RAIDs to the same host.
Since you have two servers, though, can't you move the fiber channel card in the second server into the first server? At least for the duration of combining the data?
If not then your only other option is to transfer the data over the network. It'll take longer but may be the only way.

No fiber card + cable

hi, today i installed the XServe 2 x 2 GHz Dual-Core Intel Xeon along with XServe RAID 3.5TB..
1st thing i did i open the RAID Admin and created a new array with RAID 5, i noticed that initializing is so slow and its taking forever to be ready, it goes 1% about every half an hour! is this normal?!
2nd, i didnt order the Fiber card + Fiber cables with the XServe, -didnt know they are important for setting up-, and now i cant see the Drives, and not in disk utility... is there a way to format the HD's without fibers? using the ethernet?

Maybe if you explain what you're trying to do it would be easier to give you advice that way. The XRAID has two controllers - one for each side. You'll need two cables if you use both sides simultaneously - but each card has 2 ports so you only need one card per RAID box.
When you are talking about breaking the RAID into disks are you talking about making of the actual RAIDs or splitting sides into smaller slices using either LUNs or partitions?
RAID 5 is an n-1 system so a 3 disk RAID only gives you 2 disks of storage so breaking a side into a 4 disk RAID 5 and another 3 disk RAID 5 doesn't make much sense because you're losing 2 disks worth of storage. If you want the protection of RAID 5 make either a 6 or 7 disk RAID 5 and then look into slicing it or partitioning it into smaller logical Volume sizes. Another note - the more disks you use in a RAID the faster it is so it is another argument for keeping as many disks in the RAID as possible.
Whether you make a 6 or 7 disk RAID 5 is matter of choice. If you use 6 disks and a drive fails the "hot spare" will automatically be used by the RAID to rebuild the RAID. If you use all 7 disks and drive fails the RAID will not rebuild until you physically replace the drive and if another drive fails while it's waiting you loose the data from the RAID. Most people opt for the 6+1 configuration but if you want the extra 500GB and you back-up consistently the 7 drive isn't a terrible option. Because the controllers are separate you need a hot spare for each side if you want to go that route.
If the Xserve is the only machine that will directly reference the RAID then the easiest way to make volumes from a RAID is partitioning. Once the RAID is done initializing you format it (presumably HFS+ w/ journaling) and partition it into as many volumes of whatever size you want. LUN masking is more restrictive because all the volumes need to be equally sized but it allows you physically mask off LUNs if more than one computer is "seeing" the RAID directly. If slicing the RAID in half is your goal then use whichever you're comfortable with - keeping future expansion in mind.
Hope that helps. Good luck,

100mbps multi-port fiber card for Sol10?

Does anyone know of a multi-port fiber card (PCI) with Solaris 10 support that supports 100Base-FX ? We have a requirement to provide 4 such ports for a customer, and are having a tough time finding such a beast. We can use either quad-port or 2 dual-port cards, but we don't have enough available PCI slots to use 4 single-port cards.
Basically, we're looking for something similar to this, but with support for Solaris 10:
http://www.aei-it.com/hardware/fastenet/p430fx.htm
We've been informed by the vendor that these only support up to Sol 8. We're working on getting eval units in, but are wondering if anyone has used anything similar in the past?
Thanks!
Eric

Due to customer specification constraints, media converters/switches are unacceptable. :( First thing we thought of, too. Also, 3 of the 4 ports are connecting to 100mbps digital hardware boards via UDP, so the mixed speeds probably wouldn't work out if we were to use gigabit fiber.

ATTO Fiber Card?

Our Mac has ATTO fiber cards installed in the Mac Pro, its connected to a Storage Server. Which we are running fiber as our LAN Network. Can I use the network Utility to the Ping the Server using Fiber?
Thank you

It should work. I assume you don't have any other network connections being used (such as ethernet to a WAN). Regardless, you can't hurt anything by trying.

Fiber Card failed

Dear Guru
Hope you may give me some information about the problem.
Our company SAP is ECC6.0 running on AIX 5.3 with oracle database.
Few day ago, the server log showed one of the fiber NIC card on our development server was failed. I already arranged the hardware vendor to come down to change the device next week, but before that, may anyone confirm with me whether the hardware key will be updated by replacing a new fiber NIC card? And do I need to reactiviate the SAP again?
Thanks
guodong

Hi,
If fiber card fails then hardware vendor has to play the key role. After he replaces the card he may have to change the WWN number at the EVA side . One he was able to mount the file systems with the same data then there is no need to check at SAP side. Only thing yo have to monitor the SAP application completely. Also check the run the DB verify in DB13 for any block corruptions.
Thanks,
Chaitanya

Cheapest place to purchase a Fiber card?

Anyone know cheapest place to purchase a Fiber card PCI-E 2GB and mini Gbic's?

I picked up the 4GB card PCI-x version for $299 on eBay. I always look there first. That one will fit in all of the servers I believe. Here is a link to the one I got...

4Gb Xserve Raid Card to 2Gb Xraid Fiber Channel

Greetings All,
Does anyone know if a 2x4Gb Fiber channel card will auto-negotiate down to the 2Gb level of my Xraid?
Thanks,

Yes it does. I've done it and the newest Xserve is plug and play with the old Xserve RAID.

Gigabit Fiber Card compatibility

Could someone tell me if the following configuration will work?
Gigabit Fiber NIC card in server connecting to a Gigabit Switch (Cisco Catalyst-6513 w/ WS-X6516-GBIC module) which connects to the primary 10/100 Switch.
Thanks.

Yes, that will work, but make sure you have the same flavour of Gigabit fiber in the NIC and the GBIC. Usually for a server NIC it will be 1000BaseSX.

XSAN FIBER CARD ON A QUAD G5

Guys Is there away I could use my PCI-X Fiber Channel Card on the new Quad Mac G5?
Thanks

No. It will not physically fit in the machine.
You need a PCI-Express version of the Apple Fibre Channel Card. They should be available on the Apple Store.

any idead what can it be ?

we also tried the following:
2. We compared OS/driver versions on both ( Oracle VM and Oracle Linux ) machines.
Here is the table:
Hostname OS HBA version
zil01gscapp01 Oracle VM server release 2.21 8.03.00.10.02.02_k
zil01gscmgt01 Oracle Enterprise Linux release 5.5 ( Carthage ) 8.03.01.04.05.05_k
From this comparison we concluded that VM server HBA driver should be upgraded.
We have downloaded from the QLOGIC site driver version 8.03.01.06 ( see the link )
http://driverdownloads.qlogic.com/QLogicDriverDownloads_UI/SearchByProduct.aspx?ProductCategory=39&Product=937&Os=65
By installing driver we got following error:

It looks like there is no kernel source in order to compile with the new driver, in other words Oracle VM comes wihout kernel source.
Please, your advise/opinion about all above activities and further work.

Mac Pro w/ Fiber Channel, Can it sleep with XRaid attached?

I wanted to know if the new mac Pro can fall asleep when it has an xraid attached via its fiber channel card.
My Dual 2ghz G5 does not, this is why I'm asking.
Your comments are welcomed.

Not sure, but on the 'old' one,by design, NEITHER the Fiber card and Raid card will allow 'doze' but not 'deep sleep' of the Mac Pro in order to sustain connectivity, battery charge and redundancy, respectively.
I doubt that changed.
Anyone?

Xraid Volumes not mounting

Our Xserve will not mount a raid volume. If the Fiber connection is pplugged into another xserve the mounts appear. On the problem xserve the volumes do not even appear in the disk utility. Any ideas on how to find them would be greatly appreciated. I do not think the Fiber card is bad due to the fact that the Xraid admin says the link is up.

It'll only take a few minutes to try swapping the fibre cards, and if the problem goes away, or when you open up the problem box you see the card not seated right you'd be done.

Thinking XRaid to connect 2 PowerMac towers for OD Home Folders... thoughts

Here is what I was thinking, tell me if this is along the correct lines...
Getting an XRAID (not sure of the drive config yet, suggestions are appreciated!) and dual Fiber cards, one for each PowerMac towers. Connecting both PowerMacs over fiber to the XRaid. Having a Mirrored set of drives (possible 4 total drives- mirroring 2 spanned sets- possible correct?). Then having that RAID connected to both systems, one as an OD Master, the other system as an OD Secondary.
Will this work? I want to have a central shared RAID array that both systems can see, should one box fail, and the other need to access the same data. Users entire desktop, home folder, etc will be pulled from the RAID though the PowerMac to the local desktop, which authenticates to first the Primary and if unavailable the secondary. All clients are 10.5 (latest revision) and the Servers are 10.5.4
I don't have the XRaid yet, about to order here in the next week. Would it also be recommended that if I buy a refurb that I buy an extended warranty on the unit- how often are they guys failing?

Hi
I'm in total agreement with Camelot. If I might add some views of my own? I do have some experience with your proposal but only in theory. It might be advisable to cross-post in the XSan Forum:
http://discussions.apple.com/forum.jspa?forumID=810
For perhaps more detailed answers to your questions?
Some things I have noticed about your post is you do know that Apple have discontinued the XServe RAID? Unless you already have at least one or have already purchased prior to phase out or are planning to buy second hand then you won't get any joy with any Apple branded products. Apple do recommend:
http://www.promise.com/product/productdetail_eng.asp?segment=VTrak&productid=121
Which I have never used. What I have used in a mac environment is:
http://www.united-digital.co.uk/sub_hyperstar.php
But not in the scenario you're proposing. Something you should be aware of is XSan limits you to 64 licenses. This includes MDCs, RAIDs, and Workstations. It might also include the Fibre Channel Fabric? Although I'm not sure? I'm not sure what repercussions this may have in your desire to host networked home folders as theoritically the license would be with the OD Master rather than its clients. Something to double-check on possibly? What I have seen on Apple Training Seminars is this scenario:
XSan (2 or more XServe RAIDs or any other RAID of your choice), 1xMDC and 1xBackup MDC (both XServes) and finally OD Master and however many Replicas you want depending on load. Again all XServes. Of course this is Apple's recommended configuration and assumes limitless budget. One thing for certain though is you will have performance problems if you don't dedicate something as the MDC. Although this does depend a lot on load. I guess you could have an OD Master as MDC provided you had at least two Replicas (possibly?) hosting the home folders. Again your mileage may vary.

Cluster Node as XRAID server

Does anyone know if it is possible to use a dual 2.0 G5 Cluster Node as a head server for an XRAID? I would like to have a monitor attached also. I know this will require filling both PCI slots (one video card and one fiber card). Just wondering if there are any issues with that config.

Nah, it will work.
Things to note:
* Cluster node only has one drive. If it goes, there's no mirror to fail over to.
* Cluster node comes with a 10-client version of OS X. If you're going to use it as a file server, hopefully there aren't many clients.
* No CD/DVD drive on the cluster node.
But otherwise no physical reason it won't work.

Problem with LUNs over Fiber

We have recently installed a SAN but are having a few problems with the Solaris machines we are trying to connect to it.
Hardware: LSI SAN with dual controler and 3 trays of 6x73Gb disks. Brocade fiber switch. A Sun V880 and a Sun E420 both with LSI40919O 2gb fiber cards. Both Solaris machines have resonably upto date patch clusters on them.
I can create volumes on the SAN, create LUNs on these volumes, map them to individual hosts, and (assuming the relevant entries were in /kernel/drv/ssd.conf at boot time) I can see the LUNs when I run the 'format' command on the Solaris boxes. I can label, partition, format and mount slices from these disks.
The problems occur when I want to delete or change a mapping. When I do this (delete a mapping between a LUN and a host for instance), on the Solaris box no matter what I do the disk changes to "drive type unknown". Running devfsadm (or drvconfg; devlinks; disks) has no effect. The disk is not manually configurable (it's not there after all). Only a reboot (boot -r) will actually remove the incorrect entries.
Sample output from format:

It is of course the last drive for which I removed the mapping. I can remake the mapping and the drive willonce again be available. I can add additional mappings and the new disks will be available (again assuming the relevent entry existed in /kernel/drv/ssd.conf at boot time). But any attempt to remove the mappings results in the above situation.
