Re: multipathing on HP

what sort of HP server? A Proliant? A HP9000? a HP Integrity? Myabe a HP Alpha?

What OS? Windows, Linux, HP-UX? What version?

What sort of disk array? EMC Symmetrix? HP XP? HDS USP?

You need to be much more specific...

Hi,

in 11.23
For SANs you have to install SecurePath
For LANs you have to install AutoPath


in 11.31
SAN Multipath option comes with OS

Incorrect.

>in 11.23

>For LANs you have to install AutoPath

SecurePath is for HP disk arrays only
LAN MPIO is delivered using Auto Port Aggregation. AutoPath was an old name for SecuePath

>> in 11.31
>> SAN Multipath option comes with OS

for supported disk arrays... you need to check that your disk array will work with the 11.31 storage MPIO stack

Re: multipathing on HP

Hi that is dependant on the OS Version and teh storage.

if you are using 11.23 / 11.11 of HP UNIX with HP EVA A/A or A/P storage then you need SecurePath EVA for A/A EVA disk Arrays and SecurePath EVA for A/P EVA disk Arrays respectively.

if you are using 11.23 / 11.11 of HP UNIX with HP XP A/A storage then you need SecurePath XP.

if you are using 11.23 / 11.11 of HP UNIX with EMC storage then you need EMC PowerPath
.

Multipathing with Load Balancing is an Inbuilt feature on 11.31 for A/A Disk Arrays like EVA 4K/6K/8K , XP

You shall depending on the storage that you are using need to check for the native DMP Support on 11.31.

Re: multipathing on HP

Define "multipathing"!

"...
In computer storage, multipath I/O is a fault-tolerance and performance enhancement technique whereby there is more than one physical path between the CPU in a computer system and its mass storage devices through the buses, controllers, switches, and bridge devices connecting them...."

http://en.wikipedia.org/wiki/Multipath_I/O

Thinking of pvlinks, you have always multipathing as long as you have multiple pathes to a device with configured access to this device.

Hope this helps!

Torsten.
