MSA1040 or MSA2040: Fan’s running full speed

We have had an installation of a MSA 1040 system. At the customer site, we discovered that the FAN’s kept running on full speed.

Current firmware was:  GL105P003

New firmware from HP (released 01 December 2014) fixes this problem (GL200R007).

Hopes this helps you all.

Replace faulty disk in P2000 G3 without a spare configured

  1. Wait for the array to become healthy (not degraded).
  2. Add the replacement disk and configure it as a dedicated spare.
  • Physically pull the global spare and wait for the system to start using the dedicated spare disk.
  • Replace the global spare disk. It will show up as ‘leftover’ (LEFTOVR).
  • Clear the metadata on the leftover disk (Menu: top level: Tools: ‘Clear disk metadata’).
  • Re-add the disk as a global hot spare (Menu: Top level: Provisioning: ‘Manage Global Spares’).

Disk alignment

Disk alignment is very important in every Operating system environment. But when you are using a SAN and also using VMware you should take disk alignement in account.

Above you see that the Guest OS (for example Windows) is not aligned with the VMFS and the VMFS is not aligned with the Array Blocks. Meaning that 1 I/O can result into 3 I/O’s on the storage device.

Now the VMFS has been aligned, but the Guest OS is still not. Now an I/O can result into 2 I/O’s on the storage device. Beter, but performance can still be improved.

Now all File Systems are aligned. On I/O results into 1 I/O, because all beginning of the blocks are at the same position.

Only Windows Vista, Windows 2008 and Windows XP has a trick to avoid this:

P2000 MSA from HP FAQ

The default ip address of the controllers are:
10.0.0.2 for controller A
10.0.0.3 for controller B

Default the networking setting is set to DHCP. Also the host ports need to be checked. They are standard set to Loop. Connected to a switch they should be set to Point-to-Point
