HP MSA P2000G3 ISCSCI configuration error

I have configured iSCSI adapter and I can see the storage. But not able to add as storage I am getting this error "Call "HostDatastoreSystem.CreateVmfsDatastore" for object "ha-datastoresystem" on ESXi "192.168.0.88" failed." error attached as well.
What could be the issue? What I am missing.
I restarted both host and storage but still no joy

Was the datastore you're trying to mount used for something else? Another filesystem or RDM for instance... That can sometimes cause these kind of errors, best is to wipe the disks clean before trying to use them as datastore.

I deleted the volume and recreated the volume
I removed iSCSI adaptor and added again. Still no joy

You could check the logs on your VMware host around the time you're trying to create a datastore, check hostd.log and vmkernel.log for instance ...

Let me try
It is very difficult to understand as it is not line by line.
Zephyr ICTCloud ArchitectCommented:
Yes, it demands a little of searching, you could do a "cat /var/log/vmkernel.log | grep <time-of-error>" to get close to the result ... But might skip some important parts.

If you see the disks on your VMware host, you could, for good measure, run partedUtil on the disk causing the issues, just to make sure nothing is on the disk causing issues.

For example:

#partedUtil mklabel /dev/disks/<DISK-ID> msdos

Open in new window

#partedUtil mklabel /dev/disks/<DISK-ID> msdos
This command didn't give any result.
Is that mean it is ok?

Did you replace <DISK-ID> with the correct ID of the disk you're trying to mount as datastore?

I am planning to reinstall the host machine
bcz after deleting it is not booting now
Zephyr ICTCloud ArchitectCommented:
Probably not the correct drive that was changed then... Ok, good luck... Keep us posted.

I reinstalled the host and now it is working fine.
I added the storage
What could be the reason?

Good question, something maybe got stuck with the previous atempt, sligh change in config, maybe the remaking of the Volume earlier didn't reflect through to the host... Difficult to say really.
