IPMP in ldoms Hell!
I am building a whole load of ldom servers at the moment and have become stuck trying to get ipmp working. I want to have active-standy in each domain, this works fine with solaris10u7 and probe based ipmp, but it seems there is a great feature in the latest solairs 10 update (u8) that breaks probe based ipmp. It also seems you still can't do link-based ipmp with ldoms (I have tried applying patch 142840-03 to ldom1.2 and it still doesn't work).
I don't really want to have to re-install all my new control domains with an older version of solaris, is there any way I can get this to work??
Thanks!
Perhaps you are running into this situation:
Solaris 10 Kernel Patches 141444-09 and 141445-09 May Cause Interface Failure in IP Multipathing (IPMP)
http://sunsolve.sun.com/search/document.do?assetkey=1-66-271519
that's a public sun alert document. You didn't say what exactly was broken with probe-based IPMP, but this problem (now fixed by patches) generated many, many calls to our support center.

Best practices for IPMP and LDoms?
Having read the Oracle VM Server for SPARC 2.0 Administration Guide, it seems to imply that it might be possible to configure IPMP in the control domain (i.e. between the virtual switch interfaces), eliminating the necessity to configure IPMP on each individual guest domain. Specifically, it says:
Configuring and Using IPMP in the Service Domain
IPMP can be configured in the service domain by configuring virtual switch interfaces into a group. The following diagram shows two virtual switch instances (vsw0 and vsw1) that are bound to two different physical devices. The two virtual switch interfaces can then be plumbed and configured into an IPMP group. In the event of a physical link failure, the virtual switch device that is bound to that physical device detects the link failure. Then, the virtual switch device sends notification of this link event to the IP layer in the service domain, which results in failover to the other virtual switch device in the IPMP group.
Unfortunately, when I configure IPMP in this way -- that is, with vsw0 and vsw0 in an IPMP group -- it doesn't appear to do what I'm looking for. I can ping the service domain, but not the guest domains which rely on that virtual switch.
So, this is my question: is it possible to configure IPMP in the service domain and eliminate the need to configure IPMP in the guest domain, and if so, how? Or is it always necessary to share both virtual switches with the guest domain and setup IPMP with the guest domain, as in the example in the documentation?
Thanks,
Patrick NarkinskyI'm not 100% sure, but I think that the documentation means that you can configure an IPMP group in the service domain for the vsw interfaces that are used by the service domain for its networking:
The two virtual switch interfaces can then be plumbed and configured into an IPMP group. So for example there would be vsw0 and vsw1 that are plumbed and an IP address would be assigned to the group. This does not mean the vsws that you are using for guest domain traffic.
If you would like to have a transparent multipathed networking (like MPxIO multipathing for SAN disks) for the virtual switches that provide networking for guest domains, I guess that you could use aggregates (see dladm command). The problem is or at least has been that the interfaces that are configured in aggregate must be connected to the same switch. Then there will be a SPOF. Not sure if modern network switch OS's have some kind of a capability to spread an aggregate (in Cisco world etherchannel) between two or more physical switches.
So IMHO you have to configure the IPMP group in the guest domains. -
Q: Maximum number of supported Virtual Interfaces in an IPMP group ?
This was a cluster (SC3.2) question and cannot dig out answer so far !
I'm not sure I understand the question. You only put physical adapters in an IPMP group. (I guess in an Ldom they would be 'sort of' virtual)
Anyway, I'm not sure there is a limit to the number of adapters you could have in the group. However, if you really mean how many logical interfaces can you plumb up on an IPMP group, i.e. how many services could be presented, then the answer is 1024 (IIRC). Note though that I seem to recall there was some sort of exponential increase in time taken to plumb up large numbers of IP addresses in this fashion. So practically, the answer might be near to 20-30. YMMV.

Solaris Cluster 3.3u2 configuration - Solaris Ldoms
Hi,
I've 2 sun blade T5-1B and I create 4 ldoms on each blade, also I install the Solaris Cluster 3.3u2 and its all done successfully, I did several time resource fail-over with nodes, everything seems working perfect for me as normal behavior of expected but I've an issue to test public transport testing, hereby I remove the both physical public transport cable form node1 but its didn't fail-over on node2, little confuse as its should be fail-over to node2, but not. Please let me know if where missed something to get proper fail-over?
Please advise.
regards,Hi M10vir,
this means you are running SC3.3u2 in guest domains and pulling the cables from the primary domain?
If so, this would mean that the IPMP group used in the guest domain need to get a link down that Solaris Cluster do a failover when logical hostname resources are configured. How are the network interfaces configured and what is the status of the network interfaces when the cables are removed? Furthermore does the domains recognize that the network is gone and the relevant messages are in /var/adm/messages?
Thanks,

Hell all,
Does anyone know how to determine the amount of LDOMS one can create on a T5220 with 1 Quad core running Sybase 12.5. I understand there are many factors in the type of database but in general are there best practices or guidelines to follow? Is there much overhead for the Control, service domains?
Thanks.You have posted this to the wrong forum :)
However, best practice recommendations for LDoms are that you should create domains using whole cores, so in your case that would mean 3 guests plus the control domain.
Of course your mileage may vary and you could go higher. The physical max no of domains on your system would be one per Vcpu - so 4 cores x 8 threads = 32.

Hi all,
I'm setting up a T2000 with Ldom 1.3 and have configured my control and 2 guest domains (test & prod). I'm setting up IPMP too so have created 2 vswitches and will setup IPMP in the guest domains as recommended:
VSW
NAME MAC NET-DEV DEVICE DEFAULT-VLAN-ID PVID VID MTU MODE
primary-vsw0 00:14:4f:fa:d8:09 bge0 switch@0 1 1 104,100,255 1500
primary-vsw1 00:14:4f:f8:d0:6e bge1 switch@1 1 1 104,100,255 1500and have configured my test domain with the following nics:
NETWORK
NAME SERVICE DEVICE MAC MODE PVID VID MTU
tnet0 primary-vsw0@primary network@0 00:14:4f:fa:94:26 255 1500
tnet1 primary-vsw1@primary network@1 00:14:4f:fa:e0:cc 255 1500and have just configured static interfaces on vnet0 and vnet1 in the dom for test. However, when I try and ping the IP addresses, I cannot ping vnet1. What could be the reasons for this:
$ ping -i vsw255000 10.102.255.33
10.102.255.33 is alive
$ ping -i vsw255001 10.102.255.33
10.102.255.33 is alive
$ ping -i vsw255000 10.102.255.34
no answer from 10.102.255.34
$ ping-i vsw255001 10.102.255.34
no answer from 10.102.255.34Is this a problem with the physical interface ie bge 1?
Thanks for any replies.
Stu... figured it out myself, it helps if the trunk has been setup on the network port first.

How can we move LDOM from one serve to other.
Hi,
i have an LDOM setup on a T6320 Blade with Solaris 10.
The boot image of LDOM is under a ZPool image of 32 GB.
I want to move this LDOM from T6320 to another T6340. but they don't have the shared disk or not connected to same SAN.
Sun's document talks about moving the LDOM but what i understood is it is only applicable if the virtual disks are accessable from both the servers.
Can anybody help me here ?
Thanks,

Verizon iPhone 5S PRE-ORDER HELL!! - They screwed up and dragged my situation out for 9 days!! At the end of it all I'm still missing an iPhone 5S. 9/20 @ midnight I ordered TWO iPhone 5S 16GB silver and received a order confirmation for BOTH phones and a confirmed ship by date of 9/24. NO notification of anything went wrong. 9/22 - I get a shipping notification from Verizon but only one mobile # is listed. I call Customer Care and rep just quickly and casually confirms that two phones shipped. 9/23 - I get an email saying they couldn't fulfill my order completely and that the remaining order will ship 9/30. I call Customer Care again to inquire about this and he the rep went out of his way (great guy) to confirm that two phones have shipped and that I have nothing to worry about. Said the message was generic and was mistakenly sent out. 9/25 - I receive package and find only ONE iphone!! I called Customer Care again and this time Adam helped me. After looking through things, he comes back saying he thinks the iPhone was taken out of the box before shipment, stolen!!! Had me send him all this information and said the Verizon investigation team is on it to "look" for the iphone. I asked if he could put a new order in and just exchange it for the "misplaced" iPhone. He said it was not necessary because he believes there is a iphone somewhere. 9/27- Adam leaves me a voice mail saying that it was all a misunderstanding and my iphone should ship 9/30 and he'll be on it. 9/29 - I help my wife activate her iPhone because she tried until 3am the night before with no help. While I'm on with Customer Care again she, Ida, asks how's my phone service in which I explain to her everything. She looks into it and says she sees no record of any order or tracking for an iPhone. Further says the reason one iPhone was placed on hold because a discount was applied to two devices and it could only be used for one. I told her that I've never been notified by Verizon that something went wrong until today. And this is after calling Customer Care numerous times. And NOW I find this out. She says she's going to look into it as there might be a small chance that there is an iPhone for me. She said she'll call back by 5pm and txted me her email address. 6:00pm comes and no callback. It also turns out the email address is bogus. I call Customer Care again and get another rep who looks into it and does a whole bunch more investigation. Finally she says there never was an order for my iphone and there will be no iphone shipping tomorrow. My only choice is to place a new order and I won't get it until 10/14!!! SERIOUSLY!!! ARGGGGGHHHHHHGGHGHHGG!!! Expletives galore!!! Talked to the manager Brandon and asked if they can do something for me to compensate me for all this crap I went through. I've been with Verizon for like 15 years. He kept on saying "I understand ..blah..blah.. BUT there's nothing we can do" over and over again. So I said Verizon made a mistake, detected this mistake but didn't notify the customer of this mistake, Customer Care couldn't figure it out until today, and that I'm out of luck? Does he REALLY understand? If I had known all this I could have walked to a store on 9/20 and gotten a iphone. Pre-ordering was suppose to be a convenience provided, right? And I waited because I was led to believe that some iPhone existed.. dragged along for a ride only to find out there was no iphone. And after all this, I get nothing but "I understand.... But there's nothing we can do..." So yes people Verizon stinks!!! They do not hold themselves accountable for their mistakes and expects the customer to just take it. I'll have to admit that not all customer service reps are bad (Ty, Adam, and the very last girl who helped me you guys were awesome!! Ida you could have made this list until you decided not to call me back and gave me a bogus email). Customer Care is a mixed bag and have not real authority to help you. Verizon is about to lose yet another loyal customer and his family soon. There should be some class action lawsuit for all the iphone 5s issues. Promises/Contracts made but Verizon completely failed to keep. They just jerk us along for a ride, dangling that ship date that keeps moving around.
>> Edited to comply with the Verizon Wireless Terms of Service <<
Message was edited by: Verizon Moderator"Customer Care is a mixed bag and have not real authority to help you." I worked for Verizon before it was Verizon, for several years. I think that you are entirely correct in your assessment of customer care. Reps really can't do much at all. I believe that the key function of reps is 1. hand holding and 2. punching bag. The goal is to get the customer believe that they actually DID something, and got some result! After all the talking, the customer starts to believe that something actually happened to resolved the situation. At least they spoke to SOMEONE! Picture this: the rep is on the computer, wearing a headset, and the calls are coming at them non-stop, and you have 3 minutes to convince this person that you actually helped them! But in the end, as you said, nothing happened! It is the sad truth of cs.
I am curious to see if the Moderator leaves this post on the board. -
Add Hardware in T4-2 change constraints configuration in ldom guest
The customer backup the ldom configuration before the activity but when the customer add more cpu and memory in T4-2 the ldoms GUEST
cant be initialized because they lost the original configuration , i saw in the control domain the new resorces but this modified the resorces paths in the ldom-guest
there somehow to mantain the last configuration when add more hardware without restore the ldom configuration ?

Need to connect to upgraded Oracle EBS R12 version from R11. The current ODI set up is pointing to R11, Can i use the same connection to point to R12? Please hele experts...
Rp1. in physical connections part can i use the same work schema
2. Can i use same contexts created or do i need to create everything as new and then try?
Thanks,
Rp.
Hi,
As you mentioned that you just upgraded the database, so the data is same and schema is same you can connect with the same work schema.
Yes, you can use the same contexts , but need to do Reverse Engineering for your new database.
And about data server, i think you also have no need to create new data server, if hostname,sid and port etc are same as these were with R11(consult with your DBAs regarding it) -
How to configure Solaris 10 IPMP for Oracle VDI 3.3.2
Hi,
Does anyone have an indication on how to configure Solaris 10 IPMP in a manner that supports Oracle VDI?
We have setup two servers with 2 test addresses on physical and 1 logical for the hostname of the box, but when we configure VDI the VDI database does not come up on the 2nd box. We have also tried configuring IPMP without test addresses, but it doesn't make any difference - the DB still doesn't go into the up state after configuration on the 2nd server.
Solaris 10 u9 with patches
Two physical NICs on management VLAN via 2 switches
Two physical NIcs on VDI VLAN via 2 switches
VDI 3.3.2
All hostnames are in DNS and resolve for short name, FQDN and also reverse IP lookup
The is a proposal pdf on Oracle website that mentions IPMP, so someone has done it. Just could do with a hint on how it was done so that it works.
( http://www.oracle.com/us/technologies/virtualization/vdi-design-proposal-1401195.pdf )
Thanks
PaulOK, updating this with what was causing the issue.
Not an IPMP problem this was a DNS problem. The VDI servers have access to two DNS environments, so had a DNS search path that had the domain where the VMs where going to go and another for management of the box with two DNS servers listed in /etc/resolv.conf.
We configured VDI using the FQDN for the management DNS, however the vda-config script takes the hostname of the box adds the first DNS domain from /etc/resolv.conf search entry and configures using (it seams to ignore what you put into the vda-config). When the config script comes to configuring MySQL because the names didn't match (FQDN it created by adding hostname to the 1st entry in DNS search path & FQDN that you put into vda-config command), it decides that it is configuring a "Client MySQL" instance rather than a "Slave MySQL" instance, which means the VDA DB never comes up in the out of vda-center status.
So the fix is to:
1) configure IPMP without test addresses (so traffic comes out of the correct IP and can be reverse looked up in DNS by the other host)
2) if you have multiple DNS search entries, configure VDI using the first entry in your search path as its FQDN

hello i forgot my i cloud password..anyone can help me to find my password.i already make a new apple id..but my icloud use another account..so how to reset my iCloud account plz hel me
Making a new Apple ID is not a good idea, since you have to reset the password for that Apple ID anyway. All of your purchases are tied to the Apple ID that the iCloud account was created under. So, you have to retrieve the password for that Apple ID in order to sign into iCloud anyway.
Go to Manage your Apple ID, and click on the Reset Password option (Apple - My Apple ID). Sign on with the Apple ID that the iCloud account was created under, and answer the security questions. If you do not remember the answers to the Security Questions, contact Apple Support to have them reset:

How do I create a VNIC in a 1.2 LDOM?
I have a T2000 on which I am running multiple LDOMs using version 1.2 (the newest version that supports my hardware).
# ldm -V
Logical Domain Manager (v 1.2)
Hypervisor control protocol v 1.3
Using Hypervisor MD v 1.1
System PROM:
Hypervisor v. 1.7.3. @(#)Hypervisor 1.7.3.c 2010/07/09 15:14\015
OpenBoot v. 4.30.4. @(#)OBP 4.30.4.b 2010/07/09 13:48I am running Solaris 11.1 on both the service domain & the guest domain. The guest domain will be running multiple web servers, and as such, needs multiple virtual network interfaces so I can have multiple IPs assigned to that domain.
When I try to create a VNIC in the guest domain, it fails thusly:
# dladm show-phys
LINK MEDIA STATE SPEED DUPLEX DEVICE
net0 Ethernet up 0 unknown vnet0
net3 Ethernet unknown 0 unknown e1000g0
net1 Ethernet unknown 0 unknown e1000g1
# dladm create-vnic -l net0 vnic254
dladm: vnic creation over net0 failed: operation failedAfter some searching, I discovered that this is not supported (creating VNICs in guest domains).
I am, however, able to create a VNIC in the service domain:
# dladm show-phys

vnic254/v4address static ok 192.168.1.254/24Now that I have a VNIC with a v4 IP it seems to me I ought to somehow be able to assign it to the guest domain.
Is this possible, or am I out of luck?
Would this scenario be supported if I downgraded to Solaris 10? I obviously would rather not do that, but I absolutely require the ability to have multiple IPs in my guest domain.
Thanks,
BillOK, I found one possible solution, though I don't know if it's the best (or only) one.
Instead of creating a VNIC in the service domain and assigning it to the guest, I created a new vnet for the guest.
# ldm add-vnet vnic254 primary-vsw0 guest1
# ldm ls-bindings guest1
# ldm ls-bindings guest1

So is this the best solution? Is there any limit to this? Can I add 20 more IPs this way if I need to?

Audigy 4 pro sound card HELL please advise!!!
hi all,
right i'll TRY to keep it simple!.....
BEFORE my (recently brand new) hard dri've died and caused me all sorts of probs (and ?300) my soundcard was fine it was :
windows 7
audigy 4
cubase 4
daniel k's drivers (i think OR it was the one that came with the card)
with this i HAD the option of acti've X driver OR creative asio (used this as was much much better)
SINCE it died i've tried everything for days and days of hell to get this driver on, heres the symptoms:
using the CD that came with the audigy it takes 45 mins to load and then tells me there is NO sound card fitted (tried this 3 or 4 times)..
i physically took t?he card out (twice) and it made no difference and still didnt recognise any card fitted.
i've had to system restore a few times to get it 'see' ANY driver.....i've also downloaded some drivers but same symptoms as above.
using the acti've x the latency is a prob though i have adjusted it to make it work BUT am thinking this is one of the reasons my cubase freezes / crashes / and now makes crackling noise especially when using a reverb vst.
the whole system was great B4 this and i've lost 3 or 4 days and am now at the throwing it out of the window phase.
BEFORE it handled superior drummer as a VST and midi / audio files + reverbs all at the same time NO problem.
the current set up is almost identical and in fact a tickle better than B4 so WHY wont it see a sound card ?when trying a different dirver?
HELP! Si in Brighton.ta...yes it does.
works (almost) fine with the acti've X driver, apart from telling me line/mic is NOT available....spent all day (again) trying to get the 3.8 daniel K pack on there.....came back with 'somethings wrong' meessage each time.
it just baffles me that my hard dri've
cd rom AND now (maybe) the card all ferk up at exactly the same time!
i recorded afterwards and it was fine for hours.....
