vmkfstools

[iinasprabhu]

Dear all,

I am new to vmware field. I have installed ESX Server3.

My hba card is recognised and it is vmhba1. Zoning on SAN side is also configured. Now if i run a rescan from the VI client to get ESX to scan for new storage it will show status as completed. But i am not able to see that SAN space locally. Please help in this regard.

i am using "vmfstools -C vmfs3 -S sandisk vmhba1:10:1:0" this command to format a vmfs partition whixh gives error as "operation not permitted"

Can any one guide me. Waiting for your expertise help.

regards,

Nagesh Prabhu.

Hi,

Can you run this command and check to see if all the LUNs are visible from COS

1. vmkpcidivy -q vmhba_devs

Thanks

[Santhosh_vmware]

Hello Nagesh,

get the /dev/sdx from command #esxcfg-vmhbadevs -q

then check partition 0 on /dev/sdxname is type 'fb' using fdisk

then try again

Hi Santhosh,

Thank you very much for the quick response.

The out put of vmkpcidivy -q vmhba_devs is

# vmkpcidivy -q vmhba_devs

vmhba0:0:0 /dev/cciss/c0d0

vmhba0:1:0 /dev/cciss/c0d1

can you please suggest what will be the next step. I very sorry for toubling you.

From SAN side we have allocated 400GB.

Nagesh Prabhu.

Please let me know what could be next step.

SAN side 400GB is allocated and given host type as Linux. We are using IBM FASt Storage.

Try

Please run esxcfg-rescan for LUN rescan,from the previous command it only showed local volumes

thats all ,

Hi,

also try this

vmkfstools -C vmfs3 -S storage1 vmhba0:1:0:3

regards

santhosh

[Dave_Mishchenko]

When you run this command you should see something like vmhba1:0:0 /dev/sdax. Currently your host does not see the lun so you'll want to rescan your storage and check your zoning.

root@terhitdr02 root# esxcfg-vmhbadevs -q

vmhba0:0:0 /dev/cciss/c0d0

vmhba0:1:0 /dev/cciss/c0d1

[Dave_Mishchenko]

And from the console that will be esxcfg-rescan vmhba1

[iinasprabhu]

Hi Dave,

Thanks for the suggestion, it would be great if you have some steps to create zoning so that i can create it from scratch.

regards,

Nagesh

[iinasprabhu]

Santhosh,

I have tried with both commands and output is here.

# esxcfg-rescan vmhba1

Rescanning vmhba1...done.

On scsi0, removing:.

On scsi0, adding:.

# vmkfstools -C vmfs3 -S storage1 vmhba0:1:0:3

Creating file system on "vmhba0:1:0:3" with blockSize 1048576 and volume label "storage1".

Usage: vmkfstools -C vmfs3 /vmfs/devices/disks/vmhbaW:X:Y:Z

Error: File exists

# vmkfstools -C vmfs3 -S test vmhba0:1:0:3 (Just tried)

Creating file system on "vmhba0:1:0:3" with blockSize 1048576 and volume label "test".

Usage: vmkfstools -C vmfs3 /vmfs/devices/disks/vmhbaW:X:Y:Z

Error: Bad file descriptor

#

What i need to do now.

Hi,

Can you check the DiskMaxLun settings, since ESX3.0 cannot scan LUN id more than 255.

Thanks

[Santhosh_vmware]

Hi Nagesh,

vmhba1 does not see disks,a possible San/zoning issue.

santhosh

[iinasprabhu]

Santhosh,

Thank you very much i will work on this and let you know.

Nagesh Prabhu.

[Dave_Mishchenko]

From your reply to Santhosh it does appear that the hba is seeing anything. We'll have to resolve that before you can run vmkfstools. What sort of server / hba do you have? Are you connected to SAN switch or directly to the SAN? This won't be an issue for this problem, but are the HBAs set to a type of LINCL on the SAN?

[iinasprabhu]

Hi Dave,

My Server is HPProliant -GL380 G4 and HBA card is: qla2300.

I have connected to the SAN switch through fibre. IBM FASt Storage is also connected to the SAN switch.

Santhosh, Dave and Palani

I have recreated the zoning and configured again. Now it is detecting and working fine.

Thanks a lot for all of you to the expertise guidence and help.

Nagesh Prabhu.
