ISCSI- Adding iSCSI SRs to XS booting via iSCSI [Cisco UCS]

Hello all-
I am currently running XS 6.0.2 w/ HF XS602E001 & XS602E002 applied running on Cisco UCS B200-M3 blades. XS seems to be functioning ok, except that i cannot see the subnet assigned to my SAN, and as a result, i cannot add any SR for VM storage.
The subnet and vNIC that i am configuring is also used for the iSCSI boot.
The vNIC is on LAN 2 and is set to Native
The SAN is a LeftHand P4300 connected directly to appliance ports (LAN2) on the Fabrics
Used the following commands during installation to get the installer to see the LUN.
echo "InitiatorName=my.lun.x.x.x" > /etc/iscsi/initiatorname.iscsi
/opt/xensource/installer/init --use_ibft
If i missed anything or more info is needed, please let me know.

Thanks Padramas,
I have 2 NICs that show up in XenCenter. Nic A is the vNIC associated with VLAN1 and provide the uplink to the rest of the network. The second NIC in XenCenter matches the MAC of the vNIC used to boot XenServer, so the NIC used for booting the OS is visible in XenCenter.
I have tried many different thing on my own to resolve this issue. I believe i have already tried adding a 3rd vNIC to the service profile for VM iSCSI traffic, but with make another attempt.
When configuring the vNIC for VM iSCSI traffic, do I only need to add the 3rd vNIC, or do i need to create both a vNIC and second iSCSI vNIC with Overlay vNic pointing to newly created (3rd) vNIC? My understanding is that the iSCSI vNICs are only used for booting, but I am not 100% sure.
Thanks again for the help!

Ask the Expert: Cisco UCS Troubleshooting Boot from SAN with FC and iSCSI

Welcome to this Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about Cisco UCS Troubleshooting Boot from SAN with FC and iSCSI with Vishal Mehta and Manuel Velasco.
The current industry trend is to use SAN (FC/FCoE/iSCSI) for booting operating systems instead of using local storage.
Boot from SAN offers many benefits, including:
Server without local storage can run cooler and use the extra space for other components.
Redeployment of servers caused by hardware failures becomes easier with boot from SAN servers.
SAN storage allows the administrator to use storage more efficiently.
Boot from SAN offers reliability because the user can access the boot disk through multiple paths, which protects the disk from being a single point of failure.
Cisco UCS takes away much of the complexity with its service profiles and associated boot policies to make boot from SAN deployment an easy task.

Hello Evan
Thank you for asking this question. Most common TAC cases that we have seen on Boot-from-SAN failures are due to misconfiguration.
So our methodology is to verify configuration and troubleshoot from server to storage switches to storage array.
Before diving into troubleshooting, make sure there is clear understanding of this topology. This is very vital with any troubleshooting scenario. Know what devices you have and how they are connected, how many paths are connected, Switch/NPV mode and so on.
Always try to troubleshoot one path at a time and verify that the setup is in complaint with the SW/HW interop matrix tested by Cisco.
Step 1: Check at server
a. make sure to have uniform firmware version across all components of UCS
b. Verify if VSAN is created and FC uplinks are configured correctly. VSANs/FCoE-vlan should be unique per fabric
c. Verify at service profile level for configuration of vHBAs - vHBA per Fabric should have unique VSAN number
Note down the WWPN of your vhba. This will be needed in step 2 for zoning on the SAN switch and step 3 for LUN masking on the storage array.
d. verify if Boot Policy of the service profile is configured to Boot From SAN - the Boot Order and its parameters such as Lun ID and WWN are extremely important
e. finally at UCS CLI - verify the flogi of vHBAs (for NPV mode, command is (from nxos) – show npv flogi-table)
Step 2: Check at Storage Switch
a. Verify the mode (by default UCS is in FC end-host mode, so storage switch has to be in NPIV mode; unless UCS is in FC Switch mode)
b. Verify the switch port connecting to UCS is UP as an F-Port and is configured for correct VSAN
c. Check if both the initiator (Server) and the target (Storage) are logged into the fabric switch (command for MDS/N5k - show flogi database vsan X)
d. Once confirmed that initiator and target devices are logged into the fabric, query the name server to see if they have registered themselves correctly. (command - show fcns database vsan X)
e. Most important configuration to check on Storage Switch is the zoning
Zoning is basically access control for our initiator to targets. Most common design is to configure one zone per initiator and target.
Zoning will require you to configure a zone, put that zone into your current zonset, then ACTIVATE it. (command - show zoneset active vsan X)
Step 3: Check at Storage Array
When the Storage array logs into the SAN fabric, it queries the name server to see which devices it can communicate.
LUN masking is crucial step on Storage Array which gives particular host (server) access to specific LUN
Assuming that both the storage and initiator have FLOGI’d into the fabric and the zoning is correct (as per Step 1 & 2)
Following needs to be verified at Storage Array level
a. Are the wwpn of the initiators (vhba of the hosts) visible on the storage array?
b. If above is yes then Is LUN Masking applied?
c. What LUN number is presented to the host - this is the number that we see in Lun ID on the 'Boot Order' of Step 1
Below document has details and troubleshooting outputs:

SCCM 2012 - How can I deploy Windows 7 to ANY computers when booted via NIC?

Here are the things that I would like to happen.
1. I should be able to have ANY laptops or desktops boot via network, then see the Windows 7 task sequence select and install the OS, drivers, programs. The computer name should all be "TEST" and not joined to the domain.
P.S
The reason why is because I don't want to have to know the MAC address of the computer every single time I deploy a task sequence.
Thanks for any input.

Hi,
Create your task sequence and deploy it to the special 'Unknown Computer' objects.
I personally use a collection named 'Imaging Systems' and added the 'x64 Unknown Computer' and 'x86 Unknown Computer' objects there. All my task sequences are set as available and deployed to that collection, so I can choose whatever task sequence I need
when I PXE boot a new machine.

Satellite M40-256 - error while booting via CD

Hello,
a well-known friend owns Satellite M40-256 which has Windows problem (error while updating/handling by her children).
She doesn't own an external Toshiba FDD or ODD. Also this portable has no built-in FDD. Buying one only for this issue? NO
The boot priority has been changed to: CD-network-HDD.
I've tried another non Toshiba branded ODD (in BIOS not mentioned/found)
The original ODD works/boots in another pc (via adapter) very great.
Ive tried several CD/DVDs to boot from (no error displayed): instant-Linux like knoppix, suse, other windows CDs, recovery CD, ... no success
Every time the same result: the laptop has a black screen, the ODD speeds up and after about 3 to 5 seconds windows starts with the black-white progress bar.
I also tried to press C to force booting from CD.
Some time ago, I had only access to windows in secured mode. But after uninstalling some updates it ends in a licence problem. This issue can be only solved by booting windows-cd via cd.
It has a Toshiba bios 1.00 (interesting, seems quite old).
I've trying at the moment to boot via network. Does the Toshiba show some messages about succeeding/failing at boot via network or CD?
Has setting the execution bit an influence on behaviour?
Does anybody know a solution booting windows?
Thanks in advance

Thanks for help.
I will look for an other ODD from Toshiba trying for boot.
Does the toshiba bios show messages about booting via cd or network? Even choosing network ends in a faulty Windows boot.
After choosing an item there's no message while booting
As I mentioned: the most interesting issue is ODD works/boots well via adapter in a normal pc and also after windows has been started (secured mode). But no boot possible.
I suspect meanwhile BIOS or Mainboard. But is there a chance for update in secured mode? (the only thing it starts is "secured with prompt"). Cats bites itself in tail.
BIOS also was saved with default setup. Nothing changed.
In event viewer I've found entry about probs with hard-drive and controller.
Does a destructive data processing influence the toshiba bios

HT1844 Library Issue: I just imported 2 CD's into ITunes. They show up in "Recently Added" and on my other devices via ITunes Match, but NOT in the ITunes software on the computer where I added them.

Library Issue: I just imported 2 CD's into ITunes. They show up in "Recently Added" and on my other devices via ITunes Match, but NOT in the ITunes software on the computer where I added them. They show up in the search box, but when I click on the results it just kicks me to ALL my music. I have imported thousands of songs/CD's before and this is a new one.

Something may have gone wrong with the index of the Music playlist. Making another change to the library such as downloading the current iTunes Free Single of the Week, or deleting one track from your library and reimporting it, should fix the problem.
If that doesn't work close iTunes and delete the hidden file sentinel from inside the main iTunes folder, then start iTunes again. It should run a consistency check when it starts up which ought to correct things.

60G iPod Photo Not Booting via Firewire

I cloned my hard drive to my iPod for backup, but it will not boot via firewire. I can select it in my Startup Disk control panel, so it's seeing the system. It used to work. Anyone else having problems booting? I'm wondering if this last updater broke the ability to boot via firewire.

Which iPod do you have?

Multicast WDS Imaging Not Working - Doesn't show up when booted via PXE..?

I have a lab environment setup specifically for imaging laptops via WDS. I have a stand alone Windows 2012 server connected directly to an 8-Port Cisco SG-220 8 Port switch. Nothing else is connected to this server and it is not being
used for anything else. The server is running DHCP and WDS. I can boot laptops via PXE and connect to the WDS server to deploy the images through standard WDS imaging. However, I have not been able to get Multicasting to work. I
have never used Multicasting before and have read through the documentation but must be missing something. This is what I've done:
1. In the WDS server I right click on my deployment image and select 'create multicast image' then go through the prompts to create an auto-cast image.
2. The Multicast image is created and shown as 'waiting' on the WDS server.
3. The Cisco router is brand new out of the box, the only configuration I did was to enable IGMP snooping. I did not make any other changes to the setup of the switch.
4. I boot a target machine via PXE using the same Boot Image that I always use. It loads to the screen where I can select the image I want to deploy but it never shows the multicast image as an option. I only see the regular image I had previously
been using.
I'm not sure what else I'm missing in order to get the target machine to connect and image using the multicast image.
Here are a few screen shots of what I have setup:
Here is the multicast image created on the server
Here is the Cisco Router configuration:
Here is the NIC card configuration on the server:
This is the target laptop booted via PXE but it never shows the multicast image as an option.

Hi AdamNYC31,
The multicast feature used by WDS uses Internet Group Management Protocol (IGMP) version 3. Your network switches will need to support this, and you’ll need to configure them
for multicast. Please refer the following similar thread check each step Aaron Tyler and Ron St and Ankit Oberoi offered solution.

PXE boot via Cisco router

We have a need to netboot a PC with Linux via a Cisco router (I.E. PXEboot).
We have copied the PXE linux.cfg files to the Cisco router's flash, (Cisco 2821, IOS Advanced Security 15-1.2-T1).
We have setup the router as a TFTP server with defaulted path as tftp-server flash:tftpboot
From the pc's CMOS, we selected PXE boot.
With "debug ip packet detail", we can see the DHCP request from the PC.
We cannot however, get the router to download the Linux files to the PC.
Manually we tried:
c:\ tftp 10.0.0.1 get default - no go.
ANYONE have an idea????
Thanks
Frank

Hi Ash,
Thanks for the assistance.
The laptop is directly connected to the Cisco 2821 routers g0/0 interface.
The router is configured to be a DHCP server with the Cisco 2821 router IP address on g0/0 set in the DHCP configuration to be the default router. The router’s IP address is excluded from DHCP. (10.0.0.30)
If the laptop’s bios is set to PXE boot, it seems to receive an IP address from the router I.E. 10.0.0.1– verified by statically assigning another pc IP address 10.0.0.1– the 2nd pc receives an error of IP address conflict. Then set the second pc to obtain its’ IP address via DHCP, and while running debug ip packet detail on the router, I see the router running through the DHCP assignment process and finally assigns the 2nd pc 10.0.0.2.
So needless to say, I believe the DHCP setup is functioning correctly.
The problem we have at this point is nailing down the TFTP-server function running on the Cisco 2821 router.
We were able to create the directory tree on the Cisco 2821 routers flash and then copy the correct files into each directory within flash.
Using WinXP DOS prompt, tftp does not seem to function.
With debug ip packet detail running on the router and Wireshark running on the PC, we run from a DOS window c:\tftp 10.0.0.1 GET \default. No matter how we specify the path, end result is an error of some kind.
We watch debug and wireshark display the communications of the PC and router talking, but cannot seem to get the requested file.
Perhaps WinXP tftp server is flawed.
If we load TFTP32 and attempt to send and/or receive a file from flash, works fine.
The router tftp config is as:
tftp-server flash:/tftpboot/dsl/pxeboot.cfg
The actual files name is "default" and is found on the Cisco 2821 flash:/tftpboot/dsl/pxeboot.cfg directory.
No ACLs on the Cisco router and the router is pretty much right out of the box.
Firewall is disabled on both PCs.
Ping to/from the PC/router works fine.
Thanks again
Frank

Cisco UCS C220-M3 Server doesn't boot after adding Intel I350 Quad Port NIC

Hello,
We have purchased 2 Cisco UCS C220-M3 rack mounted servers (Single Processor) that have a dual port I350 LOM. We also purchased two Intel I350 Quad Port NICs to expand the available ports on each server from 2 to 6.
The problem we are facing is that the server will not complete the boot process unless we disable either the LOM or the Quad Port NIC. We have tried numerous settings in the BIOS area but we haven't managed to have them both working.
The I350 Quad Port NICs are from Intel and not from Cisco and we are running the latest FW/BIOS on the Servers as of March 10 2015.
We have followed the steps described in the installation guide to install them.
Could you provide some light in this situation please, what are our options?
P.S. Although the LOMs are I350, the MAC Address Vendor is Cisco, is it possible that Cisco servers accept only Cisco Branded Expansion Cards?
Thank you,
George

Hi Shawn,
At least I'm not the only one having the same problem!
You are trying to use the cards with the LOMs enabled?
Which screen are you referring to in the first paragraph of your message?
Mine sits in BIOS POST for about 10 minutes and then resets itself....
We are also waiting for an answer from Cisco, so any findings/news will be posted here.
Thanks,
George

Monitoring Cisco UCS Manager via HP System Information Manager 7.1 (SIM)

I am working with a customer to configure HP System Information Manager 7.1 (SIM) to monitor their Cisco UCS Manager.
The customer is looking to monitor the following:
- CPU Utilization on manager, blades, servers, etc...
- Memory utilization
- Network utilization
- System inventory
Alerting is needed for the following:
- Hardware failures: memory, power supply, drive, etc...
- Predictive failures
- Alert messages
I have the list of all the MIBs provided by Cisco but an having the following issues while loading them into HP SIM.
While loading MIB "CISCO-UNIFIED-COMPUTING-TC-MIB" I get the following error message:
Line 128: Error defining object: expected a label, found reserved symbol {
Line in MIB: SYNTAX Gauge32 {
Guage32 is imported from SNMPv2-SMI MIB
To get past this error I found a version of the MIB that removes all the textual conventions that where causing errors. I have attached the fixed MIB file to this discussion. With the fixed version of the MIB installed in SIM everything compiles and installs except the following two MIBS. CISCO-UNIFIED-COMPUTING-NOTIFS-MIBCISCO-UNIFIED-COMPUTING-CONFORM-MIB Questions:
1. Is there any way to get the CISCO-UNIFIED-COMPUTING-TC-MIB MIB to install correctly into HP SIM?
2. Is my MIB load order setup correctly?

Conectar Cisco UCS via Nexus a NFS via IP

Tenemos una solución Cisco UCS la cual esta conectada a los Switches de Agregación Nexus y cuando se trata de conectar un o unos ServidoresVirtuales o SX a un NFS via IP no establece la conexión generando time-out, pero si la solución Cisco UCS es conectada a unos 6500 que se comportan como unas extensiones del Nexus, si se establece la conexión sin problemas.

Si efectivamente tenemos este problema, los UCS conectados a través del Nexus llegan a establecer la conexión a los NFS luego de varios intentos se establece, cuando se hace la consulta de información se vuelve extremadamente lenta , los nexus en nuestra red son los Switches Cabecera de Acceso manejan la capa 3 del Datacenter y se encuentran conectados a ellos 4 Switches 6513 vía vpc como extensiones en capa 2, la conexión de los Fabrics de los UCS conectados tambien via vpc hacia ambos nexus, cuando se tenían conectados los fabrics en los 6500 la conexión hacia los NFS se establecía normalmente, tuvimos que sacar los servidores que requieren este tipo de conexión a unos Blade de IBM que están conectados a los 6500

Cisco UCS iSCSI boot question

I am having trouble with getting this to work. I don't control the iSCSI side of the equation so I am just trying to make sure everything is correct on the UCS side. When we boot we get an the "Initialize error 1"
If I attach to FI via ssh I am able to ping the target ip's. The SAN administrator says that the UCS has to register before itself (which isn't occuring) prior to him giving it space. Everything I have seen the LUN's and Mask are created prior to boot...is this required?
Thanks,
Joe

UCSM version
2.0(2r)
We have another blade the other chasis that has ESX installed on the local drive and is using the iSCSI SAN as it datastore, therefore I know I connectivity to the SAN. The storage array is a emc CX4-120.

Adding Purchase Delivery Note with SerialNumbers via DI Server

I try to add Purchase Delivery Notes via DI Server. It already works for items that do not need serial or batch numbers. But if I try to add a PDN with an item that needs such numbers, I'm getting an error that the line of the item cannot be added without these numbers.
Then I tried to add SerialNumbers to my request, but I am still getting the same error.
The xml template for the SerialNumbers part looks like this:
<SerialNumbers>
<row>
<SystemSerialNumber />
<ManufacturerSerialNumber />
<InternalSerialNumber />
<BatchID />
<ExpiryDate />
<ManufactureDate />
<ReceptionDate />
<WarrantyStart />
<WarrantyEnd />
<Location />
<Notes />
<BaseLineNumber />
</row>
</SerialNumbers>
Can someone explain me, how to use it?
What are the mandatory fields?
What is <BaseLineNumber>? Is it the line number of the item in the purchase delivery note?
Do I have to include <SystemSerialNumber> or will this number be generated automatically by SBO?

Hi Nico,
you should use the SDK Help Center to determine the mandatory fields...
When creating an incoming document (Purchase Delivery Note) with serial numbers using the DI API I assign the InternalSerialNumber property only and this works.
The only Mandatory field when creating an outgoing document is SystemSerialNumber which is the unique key for a serial number...
As a side note, I am still experiencing some strange behaviour trying to use the DI API to create documents using serial numbers. I am in contact with SAP regarding this but am getting very slow responses...

Adding additional FX0 ports on uc540 via gateways

Hi,
Our sales rep has sold a UC540W-BRI-K9 to a customer but the customer doesn't have any BRI connections, they use PSTN lines.
The issue is that they have 7 PSTN lines. We can purchase a 4 port FXO interface card but it's not enough to connect all the PSTN lines because the UC540 has only one expansion port..
I guess the only option is to purchase a gateway device to allow the additional FXO.
My question is, which media Gateway is supported on the UC540 via CCA programming?
I know that SPA8800 is supported on the UC540 with the new software pack but it's only for the FXS ports.
Are there any other devices?
Regards
Raymond

Hi,
I am looking for possible solutions for adding an additional FXO line to a UC540 as well. Mine already has the additional VIC2-4FXO module and all FXO ports are used. From reading the Manuals, Release Notes, and Forums, it sounds like the 8800 will only support additional FXS ports. I have not found a solid answer as to why that is. It seems like it would be a hardware/platform overload issue for the UC540 to support more than 8 FXO lines. Is this assumption accurate or is there something we can do about it?
