Adding Hard Disk Drives

To add hard disk drives, follow the steps below. The hard disk drives should be added with the power of the
CPU/IO module 0 and 1 turned on.

2.5.1 Inserting Additional Disk Drives

Insert additional disk drives into empty slots in the order of the slot number from lowest to highest. Note that
two disks should be inserted into the correct locations to become a pair of slots that supports the mirroring
process.

2.5.2 Configuring a RAID Device

This section describes how to configure a new RAID device on the added disks.
1. Run esxcli -s <ESXi host IP address> storage mpm list.
2. Check the added disks in the information displayed.
The following is an example that two disks are inserted into a pair of slots for the slot 1.
# esxcli –s xxx.xxx.xxx.xxx storage mpm list

mpm0 : 143066368 blocks (139713 MB) [2/2]
\_ vmhba100500:C0:T0:L0 (10/40/1)
\_ vmhba110500:C0:T0:L0 (11/40/1)
Unused disks:
- vmhba100500:C0:T1:L0 (10/40/2)
- vmhba110500:C0:T1:L0 (11/40/2)
3. Configure a RAID device for a pair of the added disks (unused disks).
Specify the RAID device name and kernel device name that represents the relevant disk in "esxcli
storage mpm create". When the progress is no longer displayed and both kernel devices show [in_sync],
the synchronization is completed.
# esxcli –s xxx.xxx.xxx.xxx storage mpm create –v mpm1
--disk1=vmhba100500:C0:T1:L0 --disk2=vmhba110500:C0:T1:L0
<<<Make sure that the RAID device is configured
successfully.>>>
# esxcli –s xxx.xxx.xxx.xxx storage mpm list

Important
These operations must be performed by the root user.
Note
If the target disk drive has a data contained in it, the existing data will be erased by
configuring RAID system. Make sure that the target disk drive does not contain any
necessary data.
