We are looking at running MPIO for it's redundancy and load balancing benefits. Does anyone know what pieces of software or modules are needed on the VIO server to get load balancing to work. Remember we are using EMC's DMX3500 storage system. We no longer want to use Powerpath. :rolleyes: ... (2 Replies)
Hi All,
The path requires me to go Single User mode. On single user mode, the patch still won't continue:

Please merge the existing /etc/default/dhcpagent with the
patched version of /etc/default/dhcpagent shipped with this... (2 Replies)
Hi folks,
does anybody have a link to a documentation how to implement native MPIO on AIX? We are using EMC PowerPath and Datacore SanSymphony/Cambex for this so far and I wasn't able to find a good description on that topic. All I know so far is that mkpath, chpath and lspath are used to... (3 Replies)
Hello All,
After creating lpp_source/spot from AIX 5.3TL6-07 DVD on the NIM(AIX6.1), I went online and download the fix pack for reaching TL8-04. (it was less than 200Mgegs total)
then I did define a newer lpp_source530TL8-04 via a copy from the older lpp_source530TL6-07 (I diduse a command... (2 Replies)
On a particular LPAR, I was running AIX 5.3 TL 3. On Monday I did an update of the LPAR to 5.3 TL 9 SP2. The install was smooth, but then I ran into a problem.
The MPIO driver does not work with LSI's StoreAge (SVM4). I did some looking, and looks like
5.3 TL3 = IBM.MPIO 5.3.0.30

Hi,
we have a vew boxes using MPIO and they are connected to some virtualization software managing some disk subsystems, offering volumes to the AIX boxes.
Sometimes when a cable has been plugged out for a test or when a real problem occurs, using lspath to show the state of the paths shows... (8 Replies)
Hello,
we are planning to deploy some of our databases on AIX/LPAR based servers (we didn't bought it yet ...). IBM's engineers says that if we want to boot them from SAN the hardware array has to be compatible with MPIO but they don't want to deliver any document with list of arrays supported... (5 Replies)

dpns_opendir
DPNS_OPENDIR(3) DPNS Library Functions DPNS_OPENDIR(3)NAME
dpns_opendir - open a DPNS directory in the name server
SYNOPSIS
#include <sys/types.h>
#include "dpns_api.h"
dpns_DIR *dpns_opendir (const char *path)
DESCRIPTION
dpns_opendir opens a DPNS directory in the name server to be used in subsequent dpns_readdir operations. A dpns_DIR structure and a buffer
to cache the directory entries are allocated in the client API.
path specifies the logical pathname relative to the current DPNS directory or the full DPNS pathname.
RETURN VALUE
This routine returns a pointer to be used in the subsequent directory function calls if the operation was successful or NULL if the opera-
tion failed. In the latter case, serrno is set appropriately.
ERRORS
ENOENT A component of path prefix does not exist or path is a null pathname.
EACCES Search permission is denied on a component of the path prefix or read permission is denied on path.
EFAULT path is a NULL pointer.
ENOTDIR A component of path prefix is not a directory.
ENAMETOOLONG The length of path exceeds CA_MAXPATHLEN or the length of a path component exceeds CA_MAXNAMELEN.
SENOSHOST Host unknown.
SENOSSERV Service unknown.
SECOMERR Communication error.
ENSNACT Name server is not running or is being shutdown.
