Tech Note 21806

PRODUCT: ClearCase
OS:    Solaris
DEFECT #: N/A
PATCH #:
REFERENCES:

CREATED:  1-OCT-2001
REVISED:

SYMPTOM:Problem when views or vobs are on NetAPP/EMC NAS  with Solaris
servers.

CAUSE:  SUN has caused a defect in synchronous I/O  via a series of
patches.

ClearCase sites that use a certified Network Attached
Storage device to hold VOB or view databases served by
a ClearCase host running Solaris 6, 7, or 8 must not
apply Solaris patch number 105720-17 to the VOB or view
server host. This patch introduces a defect in Solaris,
documented in Sun case number 36381458 (close, EAGAIN),
which causes protocol failures that could put VOB or
view data at risk.

Sun has acknowledged the defect and made the following fixes available:

    OS Version  Fix
    -----------------------------------------------
    Solaris 8   Solaris patch # 108727-06 (or later)
    Solaris 7   binary fix
    Solaris 6   binary fix

RESOLUTION:
The Solaris bug which is  actually getting fixed is 4349744.
There are others out there, but they're all  basically duplicates of
this one.

The bug is fixed in Solaris 8 with patch 108727-06, and the current
version of
this patch is 108727-08.

 Patches for Solaris 7 and Solaris 2.6 should be coming
shortly. If you, or your customers are running into this issue on either
5.7 or  5.6,
 I would strongly recommend opening a case with SUN and asking for the
binary
fix, or t-patch to provide relief until the 'real' patch is released.
