Potential issues with vdisk multipathing in LDOMs?

edited Apr 25, 2014 1:54AM in Oracle Solaris System Administration (MOSC) 4 commentsAnswered ✓

Current LDOM 3.1 supports multipathing for vdisks across multiple IO domains, which provides for resiliency across IO domain failures. I was told this has following potential pitfalls:

  1. it is not possible to see which path is currently being used by guest domain
  2. when the "primary" path fails and guest domain reboots, it will attempt to use the primary (i.e. failed) path and fails to boot

While the former is more of a cosmetic issue, the latter is rather bad. Anyone is using vdisk multipathing in real life and can comment on these statements? Thank you!

Howdy, Stranger!
