VMware ESXi – expand RAID and resize VMFS datastore – also on non-HP server hardware

Recently, I extended my RAID 5 array with 2 extra disks from 3x 146GB to 5x 146GB, creating thus a logical RAID 5 volume of (5x 146 – 146=) 584GB. Since I didn’t want to move my VM’s to another box and reformat the datastore, I gathered all the info on the internet and made this manual.

Notes:

    * All the instructions are executed on a whitebox (i7 3770) and a SmartArray P400 controller.
    * I already modified the HP ESXi tools to be able to run on non-HP hardware.
    * It is highly recommended that you backup all your VM’s before executing a single command.
    Everything worked fine for me but one error in a command could lead to a complete data loss of everything!
    * To see the rebuilding status, HP has a tool called hpacucli which allows you to control the array and see the status of it out of the ESXi console.
    * I’m NOT responsible for YOUR mistakes. See note 3.

This is my old situation:

The steps:

– Add disks to your RAID array using ACU (offline boot CD)
hpacuoffline-9.10-22.0.iso

Explaining how to add disks is beyond the scope of this guide.

If you’re using non-HP server, get these modified HP tools:
hpacucli-9.10-22.0-esxi_mod.vib
hpbootcfg-01-01.02-esxi_mod.vib
hponcfg-04-00.10-esxi_mod.vib
char-hpilo-500.9.0.0.9-esxi_mod.vib

– Install HP tools on your non-HP ESXi server

scp *.vib root@esxserver:/tmp/
ssh root@esxserver
esxcli software vib install -f -v /tmp/hpacucli-9.10-22.0-esxi_mod.vib
esxcli software vib install -f -v /tmp/hpbootcfg-01-01.02-esxi_mod.vib
esxcli software vib install -f -v /tmp/hponcfg-04-00.10-esxi_mod.vib
esxcli software vib install -f -v /tmp/char-hpilo-500.9.0.0.9-1OEM.500.0.0.434156.x86_64-esxi_mod.vib

OR

– Get HP’s ESXi5 Offline Utilities
hp-HPUtil-esxi5.0-bundle-1.3-6.zip

– Install HP tools on your HP ESXi server
scp hp-HPUtil-esxi5.0-bundle-1.3-6.zip root@esxserver:/tmp/
ssh root@esxserver
esxcli software vib install -d /tmp/hp-HPUtil-esxi5.0-bundle-1.1-38.zip

After installing the tools, reboot ESXi server. Login again on your ESXi server using SSH or console.

– Check and expand logical drive to max
/opt/hp/hpacucli/bin/hpacucli controller slot=18 show config
/opt/hp/hpacucli/bin/hpacucli controller slot=18 array all show detail
/opt/hp/hpacucli/bin/hpacucli controller slot=18 logicaldrive 1 modify size=max
/opt/hp/hpacucli/bin/hpacucli controller slot=18 array all show detail
If you don’t know your controller slot number, use
/opt/hp/hpacucli/bin/hpacucli controller all show config

Reboot ESXi server. Login again on your ESXi server using SSH or console.

– Get the ID of your VMFS datastore
vmkfstools -P “/vmfs/volumes/datastore-nameIn my case:
Partitions spanned (on “lvm”):
mpx.vmhba1:C0:T0:L0:3

– Get the starting sector size of the VMFS partition
partedUtil getptbl “/vmfs/devices/disks/mpx.vmhba1:C0:T0:L0″

In my case:
3 10229760 573367046 AA31E02A400F11DB9590000C2911D1B8 vmfs 0

– Find usable sectors (free space)
partedUtil getUsableSectors “/vmfs/devices/disks/mpx.vmhba1:C0:T0:L0

In my case:
1146733318

– Resize VMFS partition
partedUtil resize “/vmfs/devices/disks/mpx.vmhba1:C0:T0:L03 10229760 1146733318

– Grow VMFS partition
vmkfstools –growfs “/vmfs/devices/disks/mpx.vmhba1:C0:T0:L0:3” “/vmfs/devices/disks/mpx.vmhba1:C0:T0:L0:3

Yes, you need to specify twice the same partition.

– Refresh the datastore in vSphere

New situation:

Done.

Windows 2008 R2 Server & Windows 7 Pro: Unidentified network unchangeable

After installing Windows 2008 R2 inside VMware, I changed the network driver from E1000 to VMNET3. No problem, Windows 2008 R2 recognized the new adapters after a reboot. I only had to change the DHCP IP address to fixed IP. And then the problems started: apparently Windows 2008 (or Windows 7) won’t let you change the network location as soon as it has put the network in the ‘Unidentified network’ category. Trying ‘to fix’ this problem using the Windows ‘Diagnose’ tool just removed the fixed IP address and put it back on DHCP (and strangely, now the network category is Public).

This, of course, sucks.

However, this little trick should work:

1. Start –> run –> MMC –> press enter

2. In MMC console , from menu file select Add/Remove Snap-in

3. Select Group Policy Object editor –> Press Add –> select Local computer –> press OK –>press OK

4. Open Computer configration –>Windows Settings –>Security Settings –>select Network list manager policies

5. Double click –>Unidentified networks

Then you can select the option to consider the Unidentified networks as private.

This worked for me !
