ESXi 4.1 client does not see iSCSI storage, IBM BladeCenter S

Hi all,

deploying IBM Bladecenter S with 5 SAS disks, 2xIBM Bladecenter HX5 blade servers with ESXi 4.1 embedded hypervizor.

i have enabled iSCSI software initiator and it gets IQN without any problem but i do not see any targets-devices-paths when i refresh. screenshot is attached.
also in IBM Storage Configuration Manager i cannot discover host. it does not discover it automatically, there is only option to create it manually but there are two fields asking for WWNs which i do not know where to get, please help, thanks

For iSCSI and NFS, you need to add a VMKernel Portgroup to your vSwitch, which is missing.

The VMKernel TCP/IP stack handles traffic for the following ESXi services VMware vMotion, iSCSI, NFS and Host Management.

Click Properties of the vSwitch0, and select Add

 Add VMKernel Wizard

Also check the following at the ESXi console (after adding a VMKernel Portgroup).

Use ping and vmkping to check you can contact the iSCSI SAN by IP Address, and if you are using selective presentation on your LUNs, ensure that the newly created iSCSI Initiator, is added to the LUNs for access.

i did it, no change.
in my configuration i have SAS Connectivity Card for each blade server which is used for storage connection. in internet and official guides i saw this info: "The SSD expansion card is required to support SAS Connectivity Card" and also "IBM Blade HX5 does not have an onboard LSI controller. SSD Expansion CArd required for SSD or SAS Connectivity". i do not have any SSD Expansion card, does it affect my servers' operation?

You will need to login to the ESXi server's console.

Have you also set the IP address of the IP SAN in the iSCSI Properties?

iSCSI software initiator, is software emaulation via ethernet.

Do you have an ISCSI SAN?

Skiff-SS-N-23Author Commented:
yes, i tested from ESXi console all network connectivity, they are all OK.

what do yo mean by this?

Do you have an ISCSI SAN?
can you make it more clear? i have blade chassis with SAS disks and SAS RAID Controller module on backplane

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Do you have an SAN?

iSCSI is used to communicate with shared storage on a iSCSI SAN.

What is the IP address of your iSCSI SAN?
0
 
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
So you have no iSCSI Storage Area Network to use with ESXi?
0
 
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
if this is all you have

"i have blade chassis with SAS disks and SAS RAID Controller module on backplane"

you have no need to enable iSCSI.

Why are you enabling iSCSI, your storage is LOCAL!

I have blade chassis model IBM Bladecenter S, which has embedded 12 modules for disks. They are connected through SAS. I have installed two HX5 blade servers on this chassis. They do not have local drives, they have embedded ESXi hypervisor on USB. Then what can you say about this:
 host error

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Okay, if you have no SAN, there is no requirement to setup iSCSI.

Can you see the storage controllers in ESXi, and can you add a datastore under Storage?

Skiff-SS-N-23Author Commented:
That is the actual problem. i do not see any controller or datastore, you can see below

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Can you also screenshot storage controllers?

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
After reading all your posts, you will need to use the SSD Expansion card, to present the embedded 12 modules for disks to the Blades that are running ESXi.

I have 2 of these units in operation without SSD drives so I don't know for sure about using them, but with SAS/SATA drives you will need the SAS Connectivity Module(s) in the BladeCenter.  The configuration isn't very intuitive, but basically you will need to create RAID groups, assign them LUN #'s, and then you will see the RAID drive(s) as being available to the ESX hosts.  I could never get the Storage Manager GUI to connect to the modules so I just used the command line through SSH connections to the Connectivity Modules.

on a side note; the last time I checked, vSphere 5 wasn't supported with this storage.  has anyone heard from IBM if this is an oversight or if it will be supported in the future?

Skiff-SS-N-23Author Commented:
yes, the configuration was not complete, so we had to purchase SSD Expansion Card which we omitted,

thanks again
