Solaris 10, ISALogic SCSI interface and ARCVault tape library

I put an ISALogic SCSI interface card into a SunBlade 2000, installed
Solaris 10_u4 on it and attached an ARCVault tape library. The system
see the tape but fails to see the library and the robot. The robot and the
tape are on the same scsi bus.
I followed the instructions on how to do a scsi passthrough and did a probe-scsi-all
at the ok prompt of the system.
The probe on the ISAlogic interface card sent the system into a bus error.
Any idea how I could make the robot visible on the same bus?

A firmware update on the Blade solve the problem.

Combining ufsdump and a tape library

Hi All,
I have a question with regards to multi-volume backups using ufsdump and a tape library. Reading through the ufsdump documentation, I see that it has an option "l" (lowercase L), which says "When the end-of-tape is reached before the dump is complete, take the drive offline and wait up to two minutes for the tape drive to be ready again ...". However, when I use this option, and ufsdump reaches the end of the tape, it does not offline the tape drive. It sits there, waiting for a response to the question "DUMP: NEEDS ATTENTION: Do you want to restart?: ("yes" or "no")"...at no time does the tape drive go offline, which would allow me to write a script to detect the offlining of the tape, and swap it out for a fresh one.
Basically, what i'm looking for is a way to allow ufsdump to span >1 tapes without operator intervention by having a script detect when it needs new media, and ask the library to load the next tape. However, ufsdump doesn't relinquish control of the tape drive, so I can't pop out the tape unless I kill it...
Can anyone suggest a solution to automating multi-volume ufsdumps to tape?
Thanks,
-Adam Lundrigan

I don't think you can do this AND have a variable sized output media. You will get the restart question when it gets a tape error (which you will get if you write out too much). I think the only way you can do what you want is to conservatively figure out what would fit on a tape with compression, and giving a tape length where the length*bpi will give you that figure (ie, no errors on tape writes).

Cluster and L1000 Tape Library

We are planning to purchase a tape library system for backing up the data on our cluster. I was wondering if any one ever used the Sun L1000 Tape library system with NetBackup. How do you like the L1000 and NetBackup? Is the L1000 tape library reliable? What kind of throughput do you get? We have a 2-node cluster E5500/E4500. I am planning to connect the tape library to an E250 and use it as the backup server.
Thank you in advance.

hi sjen,
it depends on the size of you databases and filesystems. the sun 250 should be ok, if you have enough memory. sometimes the network-interface (dfx) is a bottleneck.

Robotics error and issue within SL24 Tape library with Solaris 10

Dear All,
Kindly may any one help me with this issue or at least give me a hint about where to begin thinking about the solution from
I have a tape library SL24 which is attached to the server V240 my backup server on which the robotics is not seen by the veritas net backup and when I try some commands like
#sgscan
the robotics isn't discovered
the Veritas docs says that this is issue is related to the Solaris OS
so can any one give me what are the possible causes to that error ?
knowing that there is no zoning in this datacenter

Did this configuration of your V240 and the SL24 ever work?
Here's the documentation for the SL24:
http://docs.oracle.com/cd/E25510_01/index.html
Here's the documentation for the V240:
http://docs.oracle.com/cd/E19088-01/v240.srvr/index.html
I have a tape library SL24 which is attached to the server V240 ,,, attached to what? I don't think the integrated SCSI port is compatible and therefore you'll need to buy and install an appropriate HBA for the computer.
Start with the documentation.

Solaris 8: Multiple primary interfaces connected to the same network

I have a machine with Solaris 8, and it has multiple interfaces that are connected to the same network which means they all have metric 0 (1 hop) to the default gateway.
assume:
e1000g0: 192.168.30.70
e1000g2: 192.168.30.72
e1000g4: 192.168.30.74
e1000g5: 192.168.30.76
gateway: 192.168.30.65 (Cisco Router)
However, it seems like despite the fact that they have a direct connection, they seem to be using e1000g0 to access the 192.168.30.0 network to get to the default gateway and then to anywhere else.
When I send a ping to say, 192.168.30.74 (IP of e1000g4) and capture packets on e1000g0, I see the "echo reply" messages going out of it as opposed to e1000g4 even though e1000g4 is the one receiving the "echo request". This should not happen and these should be completely independent as they should all be advertising a 1 hop to that network
The outputs from netstat -rn and ifconfig -a are shown in the picture on the link below
[http://img836.imageshack.us/img836/7308/ifconfignetstathiddenip.jpg]
This gets even more confusing when I go into the Cisco router and run the command: "show mac address-table" where only the MAC address of e1000g0 is shown for the switch port it's connected to, but not for the other interfaces which are connected to the switch. Yes, all ports are active (no shut) and are pingable.
Also, the odd thing is that ALL of these individual MACs show up in the router ARP table when the machine comes up, however after sending a ping to one of them, after a certain expiry or whatever period, the MACs disappear from the router ARP table and only the MAC for e1000g0 shows up. The arp table of the solaris machine however shows all the relevant MACs of each port of the router that it's physically connected to (This is actually a Cisco Switch with the advanced IP services imagine and L3 routing turned on)
Before anyone asks: The setting local-mac-address? setting does NOT exist in my machine and it never has, but it used to work fine. Also, from the ifconfig command, once can tell that all the MAC addresses are fine.
I need to somehow assign all these interfaces equal priority and make them understand that they're physically connected to the 192.168.30.0 network and there's no need to go through e1000g0 to get to it.
This is causing a lot of problems as eventually all traffic will end up going through the e1000g0 interface and that will become a bottle neck.
Please help Thanks in advance

Ok thanks. That was a useful response.
I did think about the trunking software that is claimed to be available for Solaris 8, but it's only available if you've got paid support contract. Oracle came and ruined everything re: Sun support which is so expensive now.
The other confusion is, we never had that OR needed to configure trunking/link aggregation on this machine, so why now?
Lastly, by your explanation, this should be expected and is "normal" behaviour, which would mean that this machine was always doing this and I only just noticed it this time? I thought if you turn off ipv4 forwarding and router function in the machine, it's every interface for itself. But it's not doing that :(
So then the question is, Can I force it? I've tried a bunch of things by manipulating the tables and it seems to mess things up where nothing is getting through or it now shifts all the traffic to some other port make the problem no different
Is there a way to give equal weight to all interfaces for the traffic to go directly through them that is originating at those ports?

SP500 tape library - how many server/SAN FC interfaces do I need?

How many server or FC switch interfaces do I need to connect SL500 FC tape library? Let's say we have two FC tape drives installed. Does it mean I need to reserve 3 FC interfaces (one for robot and one for each drive)? Or there is some kind of internal hub/switch which permits to use one FC port to connect them all in a way which is implemented in SL48 library?

Hello,
if one VMWare host should run more then 2 VMs you need a Windows Server 2012 R2 Datacenter edition (unlimited versions from Windows VMs on the host) from Windows or 7 Windows Standard licenses (max. 14 VMs).
Keep in mind that processors count into the license requirements.
"...using VMware for high availability..."
This means that you should have at least 2 VMWare hosts which have the RAM and processors to run in caseof hardware problem from the other host ALL VMs.
So you are now need at least 2 Windows Server 2012 R2 Datacenter licenses or 14 Standard editions.

New SCDPM 2012 Deployment Scenario and tape Library Sharing.

Folks
I am having one SCDPM 2012 SP1 on Server 2008 R2 with one tape library. I am going to build another second DPM on Server 2012 and I want to share the same library which is on first DPM.
Before I build second DPM server I want to make some doubts clear so it does't create issues later.
Both DPM will be physical.
I am reading technet link to share tape ibrary : http://technet.microsoft.com/en-us/library/hh758124.aspx
And My queries are:
1) The tape library must be in a storage area network (SAN) environment.
>The tape Hewlett Packard LTO Ultrium-5 drive I have is attched to first DPM server through SCSI array.Dont know if it is SAN supported.
2) We recommend that the system configuration of the library server computer and all library client computers be as similar as possible, and that you do not configure any protection groups on the library server.
>As I have attached library to my first DPM server which is having 22 Protection groups with 562 datasources. Can it be promoted as a Library server? If not then what is solution for this.
3)All DPM servers using a shared library must use a similar SQL Server setup for hosting DPM databases.You cannot have some DPM servers using local instance and others using a remote instance.
>My first DPM is hosting its Database on its own (local) So should I setup SQL on second DPM localy?
4)SQL accounts should be DOMAIN accounts? On the technet link it is showing SQL failover cluster, where does it require? As image showing it is required between library clients but I will have one library server and one library client, will I needed SQL CLuster?
This was related to Tape, now other queries I have if second DPM and tape sharing deployed successfully.
1) First DPM has reached LDM records occupancy 79% and I have identified non-colocated datasources/Protection groups which are occupying larger amount of LDM. I will move/recreate these protected groups on 2nd DPM with COLOCATION so they cant use much LDMs.
a)Should I stop protection on 1st DPM and add these protection groups on 2nd DPM. Will it allow me to add since Inactive replica there would be on 1st DPM for 30days
b) Or should I Migrate these PGs?
c) What is best practice for this?

Figured it out. Since I'm on a preconfigured RDS server, the RDS Session Host role is already installed. So technically Session-based desktop deployment is already set up. It's the difference between the session host role and the Virtualization
Host roles...slightly confusing when you walk into the middle of the deployment.
It would also explain my second part of the question since the session host role is installed....

The difference between IEEE802.1Q Native VLAN sub-interface and Physical interface?

Hello
I think the following topologies are supported for Cisco Routers
And the Physical interface also can be using as Native VLAN interface right?
Topology 1.
R1 Gi0.1 ------ IEEE802.1Q Tunneling L2SW ------ Gi0 R2
R1 - configuration
interface GigabitEthernet0.1
encapsulation dot1Q 1 native
ip address 10.0.0.1 255.255.255.0
Topology 2.
R1 Gi0 ------ IEEE802.1Q Tunneling L2SW ------ Gi0 R2
interface GigabitEthernet0
ip address 10.0.0.1 255.255.255.0
And is it ok to use the physical interface and sub-interface with dynamic routing such as EIGRP or OSPF etc?
R1 Gi 0 ---- Point to Multipoint EIGRP or OSPF ---- Gi0 R2 / R3
Gi 0.20--- Point to Point EIGRP or OSPF --- Gi0.10 R4 (same VLAN-ID)
R1 - configuration
interface GigabitEthernet0
ip address 10.0.0.1 255.255.255.0
interface GigabitEthernet8.20
encapsulation dot1Q 20
ip address 20.0.0.1 255.255.255.0
Any information is very appreciated. but if there is any CCO document please let me know.
Thank you very much and regards,
Masanobu Hiyoshi

Hello,
The diagram is helpful.
If I am getting you correctly, you have three routers interconnected by a switch, and you want them to operate in a hub-and-spoke fashion even though the switch is capable of allowing direct communication between any of these routers.
Your first scenario is concerned with all three routers being in the same VLAN, and by using neighbor commands, you force these routers to establish targeted EIGRP adjacencies R1-R2 and R1-R3, with R1 being the hub.
Your second scenario is concerned with creating one VLAN per spoke, having subinterfaces for each spoke VLAN created on R1 as the router, and putting each spoke just in its own VLAN.
Your scenarios are not really concerned with the concept of native VLAN or the way it is configured, to be honest. Whether you use a native VLAN in either of your scenarios, or whether you configure the native VLAN on a subinterface or on the physical interface makes no difference. There is simply no difference to using or not using a native VLAN in any of your scenarios, and there is no difference to the native VLAN configuration being placed on a physical interface or a subinterface. It's as plain as that. Both your scenarios will work.
My personal opinion, though, is that forcing routers on a broadcast multi-access segment such as Ethernet to operate in a hub-and-spoke fashion is somewhat artificial. Why would you want to do this? Both scenarios have drawbacks: in the first scenario, you need to add a neighbor statement for each spoke to the hub, limiting the scalability. In the second scenario, you waste VLANs and IP subnets if there are many spokes. The primary question is, though: why would you want an Ethernet segment to operate as a hub-and-spoke network? Sure, these things are done but they are motivated by specific needs so I would like to know if you have any.
Even if you needed your network to operate in a hub-and-spoke mode, there are more efficient means of achieving that: Cisco switches support so-called protected ports that are prevented from talking to each other. By configuring the switch ports to spokes as protected, you will prevent the spokes from seeing each other. You would not need, then, to configure static neighbors in EIGRP, or to waste VLANs for individual spokes. What you would need to do would be deactivating the split horizon on R1's interface, and using the ip next-hop-self eigrp command on R1 to tweak the next hop information to point to R1 so that the spokes do not attempt to route packets to each other directly but rather route them over R1.
I do not believe I have seen any special CCO documents regarding the use of physical interfaces or subinterfaces for native VLAN or for your scenarios.
Best regards,
Peter

What is the diffrence between My Runnable Interface and Java Runnable

Hi folks
all we know that interfaces in java just a decleration for methods and variables.
so my Question is why when i create an interface its name is "Runnable" and i declared a method called "run" inside it.then when i implements this interface with any class don't do the thread operation but when i implement the java.lang.Runnable the thread is going fine.
so what is the diffrence between My Runnable Interface and Java Runnable?
thnx

thnxClasses and interfaces are not identified by just their "name", like Runnable. The actual "name" the compiler uses is java.lang.Runnable. So even if you duplicate the Runnable interface in your own package, it's not the same as far as the compiler is concerned, because it's in a different package.
Try importing both java.util.* and java.awt.* (which both have a class or interface named List), and then try to compile List myList = new ArrayList();

Difference between abstract interface and normal interface

Hello Friends,

What is the Difference between abstract interface and
normal interface?....The difference is that you didn't follow convention in the first case. All interfaces are implicitly abstract so you don't have to declare them as such.

INTERFACE AND EVENTS IN ABAP OO

Can some one explain me the real time need with example for use of interfaces and events in abap objects
(asking interface and events along doesnt mean that i am relating them).
<removed_by_moderator>
Pankaj Giri
Edited by: Julius Bussche on Jul 14, 2008 1:36 PM

Events :
Technically speaking :
" Events are notifications an object receives from, or transmits to, other objects or applications. Events allow objects to perform actions whenever a specific occurrence takes place. Microsoft Windows is an event-driven operating system, events can come from other objects, applications, or user input such as mouse clicks or key presses. "
Lets say you have an ALV - An editable one ...
Lats say - Once you press some button you want some kind of validation to be done.
How to do this ?
Raise an Event - Which is handled by a method and write the validation code.
Now you might argue, that I can do it in this way : Capture the function code - and call the validate method.
Yes, in this case it can be done.. But lets say .. you change a field in the ALV and you want the validation to be done as soon as he is done with typing.
Where is the function code here ? No function code... But there is an event here - The data changed event.
So you can raise a data changed event that can be handled and will do the validation.
It is not user friendly that you ask the user to press a button (to get the function code) for validation each time he enters a data.
The events can be raised by a system, or by a program also. So in this case the data changed event is raised by a system that you can handle.
Also, Lets say on a particular action you want some code to trigger. (You can take the same example of validation code). In this case the code to trigger is in a separate class. The object of which is not available here at this moment. (This case happens very frequently).
Advantage with events : Event handlers can be in a separate class also.
e.g : In the middle of some business logic .. you encounter a error. You want to send this information to the UI (to user - in form of a pop up) and then continue with some processing.
In many cases - A direct method call to trigger the pop up is not done. Because (in ideal cases) the engine must not interact with UI directly - Because the UI could be some other application - like a windows UI but the error comes from some SAP program.
So - A event is raised from the engine that is handled in the UI and a pop up is triggered.
Here -- I would have different classes (lets say for different Operating Systems). And all these classes must register to the event ERROR raised in application.
And these different classes for different Operation systems will have different code to raise a pop-up.
Now you can imagine : If you coded a pop-up for Windows (in your application logic) .. it will not work for Mac or Linux. But of you raise a event.. that is handled separately by a different UI classes for Win, Linux or Mac they will catch this event and process accordingly.
May be I complicated this explanation .... but I couldn't think of a simpler and concrete example.
Cheers.
Varun.

Firewire Interface and Microphone Choices?

Was looking to drop no more than 500 dollars on a firewire interface and less than 175 in a microphone to do some decent quality recording onto my MB (primarily trumpet, ukulele and acoustic guitar). For the interface I've been looking at the:
Apogee Duet
http://www.musiciansfriend.com/product/Apogee-Duet-Firewire-Interface?sku=234444
And for the mic, the:
MXL 992
http://www.musiciansfriend.com/product/MXL-MXL-992-LargeDiaphragm-Condenser-Micr ophone?sku=273162
Any feedback on these two products or have any other recommendations? Thanks for the help.

If you don't need a lot of inputs and outputs, but are looking for decent sound quality, the Apogee Duet seems like a good deal.
I'm not familiar with the mic.
