[pca] [[slightly] off-topic Warning]: Solaris 10 SPARC patch 144500-19 and EMC PowerPath

[Don O'Malley]

Hi Bob,

The problem here is not with the patch (or Solaris).

Without going down the finger-point route, the problem is a result of 
EMC PowerPath using private interfaces in Solaris, Oracle subsequently 
updating them and bang...
Only customers running EMC PowerPath have currently confirmed they have 
the issue. Oracle will not withdraw the Solaris 10 KU patch for this.

The following note is being added to 144500-19 to warn EMC customers 
about the issue:

     Do not install this patch on systems running EMC PowerPath, as all currently
     released EMC PowerPath versions (as of August 18th 2011) are incompatible with
     this patch.
     EMC PowerPath is using a private Solaris structure which was modified in this
     patch to fix a race condition. Applications should not use private Solaris
     interfaces as they are subject to change.
     EMC PowerPath Engineering is working on a 5.3 patch release to resolve this
     issue and have published ETA emc275344 onhttps://powerlink.emc.com, which
     contains further information.


Best,
-Don
