Today I wanted to add a new iSCSI Lun to my vSphere Lab. I got the following error:
I had this error in the past, see my previous post: . I tried the solution described in my previous post but it didn’t work in vSphere.
So I had to search for another solution. Luckily VMware released a KB document. See . In this KB document VMware uses the command esxcfg-vmhbadevs. This command is replaced with a new command called esxcfg-scsidevs.
So I ran the esxcfg-scsidevs command on the service console:
After running the command, write down the following line: Console Device: /dev/sdc. Start Parted and walk through the following steps.
Note: don’t forget to change the /dev/sdb to the device you need to fix. In my case /dev/sdc.
To change the label and partitioning scheme:
Caution: This removes the pre-existing partition table, and any data on the volume is no longer be available. Ensure you are operating against the correct disk.
- Start parted to analyze the existing partition. Print the existing partition information, taking note of the Partition Table, size, and name. Ensure this is the data intended to be removed.
Run the following commands:
[root@esx ~]# parted /dev/sdb
GNU Parted 1.8.1
Using /dev/sdb

Run the following commands:
(parted) mklabel msdos

(parted) quit- Return to the VI Client and use the Add Storage wizard again. Choose the same LUN, create a new partition, and format it with a VMFS Datastore as normal.
