Hi experts,

Is there any multipath software available with HP-UX 11iv1, 11iv2 and 11iv3. Please let me know.

Thanks

IIRC this is sold on separate media.

What array do you have?

Also it depends to which disk array you are connecting your hpux server and the firmware version of the controller if its an EVA san storage.

!correction
"In hpux v3 "
In hpux v3 pvlinks are used and hence no additional multipath software required.

>> in hpux v3 pvlinks are used

11iv3 has a new mass storage stack with built-in native multi pathing support.

All previous version are able to use PVLINKS.

I little history here for ya..

All HP-UX versions since the early 90's have supported multipathing (aka PVLinks). Some arrays require special software(an older EVAs (3K/5K) is an example) for multipath support.

There is software for load balancing that is provided (aka Autopath, and now SecurePath) which was not avaialble until the early 00's. With the release of 11i v3, they have now built load balancing in to the mass storage stack, and improved the naming and addressing schema (no more cXtYdZ, just disk1, etc).

Sincerely,

Curt
