SecurePath?

Hi All

I heard securepath has been replaced or it is not supported. Can someone tell me if that is true?

Thanks

Hi,

for the newer arrays (EVA4000/6000/8000), you do not need securepath anymore. In fact, it won't work on these arrays. You can use MPIO software (free from HP) for Windows, and native multipathing for other OSes.
For other arrays, it depends. What storage do you have, and what OS?

Stephen

If you refer to SecurePath for Active-Passive arrays - i.e. for HSG80 or EVA 100/110 (aka EVA3000/5000 @ VCS 3.028 & below) - it is still very much supported and "REQUIRED".

Newer EVAs (EVA 4/6/8K and upgraded EVA 3K/5K that are at VCS 4.X) no longer require SedurePath for Active-Passive arrays. HP i showever optionally offerring SecurePath for Active-Active Arrays -- also called AutoPath - which you can actually do without since most native and 3rd party Industry standard multi-pathing solutions are now fully supported. These are MPIO, PVLINKS an dVeritas DMP - to name a few.

However, active-active SecurePath for HP-UX (autopath) also provides load balancing across the paths, while as far as I know, "pvlinks" does not.

Thanks all for reply. So, it seems securepath has not replaced yet.
The storage is msa 1000/5000 and OS is Windows. Looking for load balancing option.

Hi,

SecurePath for Windows (Workgroup Edition) is valid for MSA1000/1500, up to a certain firmware revision. The other option is MPIO Basic, but you cannot mix the two. Either all hosts run SecurePath or all hosts run MPIO.

What do you mean by load balancing? Do you want to spread the load across both MSA controllers? Only the MSA1500 with the very latest Active/Active Firwmare can do that at the moment.
This requires MPIO-Full Featured (free to download), and will not work with SecurePath (AFAIK).
Otherwise the MSAs work active/passive. All I/O goes to one controller, and the 2nd controller is standby.
I have no idea when Active/Active Firmware for the MSA1000 will be available.

Stephen
