Adding a disk to the ESXi host fails with the error: Call "HostStorageSystem.ComputeDiskPartitionInfo" for object "storageSystem" on ESXi failed

Products

• VMware vSphere ESXi

Issue/Introduction

Symptoms:

• Cannot add a disk to the ESXi host
• Adding a disk to the ESXi host fails
• You see this error:
  
  Call "HostStorageSystem.ComputeDiskPartitionInfo" for object "storageSystem" on ESXi failed.

Environment

VMware vSphere ESXi 5.5

Cause

This issue occurs when you are trying to add a disk that has a partition table defined on it.

Automatic checking when adding a disk prevents from adding a disk that contains a valid partition table.

Resolution

To resolve this issue when there is a left-over partition on a disk, delete the partition.

Notes:

• The NAA ID used in these steps is an example ID and must be replaced by the actual ID found in step 1.
• This procedure removes the partition information on the disk and makes any data on that partition inaccessible.
  

To delete the left-over partition on a disk:

1. Run this command to find the disk name:
   
   

   # esxcfg-scsidevs –l
   
   You see output similar to:

   VAAI Status: unsupported
   
   

2. After finding the disk name, check if the disk has any partitions on it using this command:
   
   # partedUtil get /dev/disks/naa.6b083fe0c2c8f6001b891af71508e8d8
   
   You see output similar to:

   240614 255 63 3865468544
   1 2048 3865464831 7 0

   In this case, this disk has 1 partition.
   
   

3. Run this command to delete the partition:
   
   # partedUtil delete /dev/disks/naa.6b083fe0c2c8f6001b891af71508e8d8 1
   
   Note: Ensure that you have do not require that partition further and have the correct disk before doing this.
   
   
4. Run this command to confirm that the disk does not have any more partitions:
   
   # partedUtil get /dev/disks/naa.6b083fe0c2c8f6001b891af71508e8d8
   
   You see output similar to:
   
   240614 255 63 3865468544
   
   
5. Retry adding the disk to the ESXi host.
