Hi,<br />
<br />
what is &quot;failover&quot; for you in regard to VIO disks?<br />
<br />
Could it be that you mean SEA failover, which is for virtual Ethernet, not for disk paths?<br />
<br />
Anyway, redundant disk paths in LPARs are managed by AIX's native MPIO, which<br />
will present one single disk per LUN to the OS, regardless of the number of paths used.<br />
<br />
If one path fails the other paths(s) will almost seamlessly take over, in-flight blocks will be retransmitted, that's all.<br />
<br />
So using paths over redundant VIOs is of course a valid setup for ASM.<br />

Hi,

what is "failover" for you in regard to VIO disks?

Could it be that you mean SEA failover, which is for virtual Ethernet, not for disk paths?

Anyway, redundant disk paths in LPARs are managed by AIX's native MPIO, which
will present one single disk per LUN to the OS, regardless of the number of paths used.

If one path fails the other paths(s) will almost seamlessly take over, in-flight blocks will be retransmitted, that's all.

So using paths over redundant VIOs is of course a valid setup for ASM.

The LUNs are presented to both VIO server. &nbsp;On &nbsp;each VIO &nbsp;the hdisks &nbsp;have the &quot;no_reserve&quot; and &quot;PVID = yes&quot; attributes set<br />
<br />
If any &nbsp;VIO server is shutdown or &nbsp;fails the SAN storage should not be impacted with only ASM &nbsp; with out using RAC &nbsp;corrrect ?

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
