Re: xp128+ibm p650 AIX

Hi,
Long time I touched aix but from what I see here:
1) yes
2) We have HDS equivalent (HDLM), since we have HDS bays... You need to have the functionality see below...
3) I dont think so (using HDLM or equivalent like autopath...)

About 2) I have seen that since aix 5L (>5.2)
There is an IBM option (no idea if this is to buy though...) called AIX MPIO, this features allows multiple path to devices so you can define alternate paths for failover purpose (a must with these bays to have duall acces since one path can be brought down for microcode update...)


All the best

Re: xp128+ibm p650 AIX

Yes, the XP128 supports IBM's MPIO - MPIO is the equivelent of PV-Links.

There is a AIX MPIO quick-connect guide available - it's an HP Restricted document, so talk to your HP support team to get a copy - I can't post Restricted documents here.

Good luck,

Vince
