Or, How to extend exiting RAID5 storage pool in CISCO C240
Rack Server?
Descriptions/Scenario: This is very generic requirement that, sometime we
may need to extend the exiting server’s drive space due to space crunch. If
it’s a virtual machine, your life is easy but if it’s a hardware machine, you
need to go with lots of things (purchase new HDDs, extend existing RAID space,
wait for successful reconstruction completion, expand the logical drive associated
with the RAID group you are extending etc..).
In my case, I have a CISCO
C240 rack server where I have two RAID groups. RAID1 for OS and RAID5 with one
hot-spare drive for data.
The RAID5 data drive in the
OS is full and having no space. I have purchased some additional HDDs and
inserted in empty slots of my CISCO Serer.
Lets see in below steps what
else to be done.
Steps:
Login to CISCO Server management
console (CIMC) and verify if all the hardware components are functional well
without any error.
Select RAID5 pool
> Click on Edit Virtual Drive
Click OK to
confirm if prompted in the Pop-up window
Select RAID Level (5)
Select all the “Unconfigured Good” newly inserted
drives > Click on Save Changes
The configuration process
will be started now
Wait for reconstruction task to be completed (it may take
longer).
Note: Please
check if all the hardware components are working well. Here we got a Moderated Fault because of
reconstruction job. Don’t worry, once the reconstruction will be completed, the
fault will go away.
If there are other components which are showing fault
status, you must take action on that with the help of CISCO Support guys.
Upon the successful completion of “Reconstruction” you can
extend the disk from OS inside.
