I have same lun (hdisk3) assigned to 2 vios server (dual vio server) and this is mapped to the client lpar. I have sddpcm on the VIO.
On the VIOA, the attributes for fscsi1 and fscsi3 are set to fast_fail and dyntrk is set to yes
Now, if I do a lqueryvg -Atp on the hdisk3, I get a "DISK OPERATION ERROR" and a related fscsi1.
I am trying to understand , if this is due to scsi reserve issue or is it a zoning issue. With sddpcm, the hdisk reserve_policy is set to no_reserve by default.
I still have to find out if any errors are reported on the switch.
Can anyone recommend me some reading material surrounding how AIX handles LUNs:
- with and without MPIO installed
- with and without SDD or SDDPCM installed
Where does lspath sit in all of this (MPIO layer?). Can a system be built with just MPIO software? Is MPIO software even needed?
I guess... (0 Replies)

Hi folks.
We want to move a "physical" AIX box to a VIOed LPAR. The physical box is running SDD with disks from a DS8300. I want to be able to reattach those LUNs from the DS8300 to my VIO server which is running SDDPCM and then assigned them back to my AIX LPAR. Any thoughts about this?

I am planning carving out dual VIO servers on a P750 based and would like to know how to allocate internal disks to the VIOS. This has 4 internal disks and I would to assign 2 disks to each VIO.
This is what I was thinking of assigning . Any advise?

Hi
In the vio server when I do # lsattr -El hdisk*, I get a PVID. The same PVID is also seen when I put the lspv command on the vio client partition. This way Im able to confirm the lun using the PVID.
Similarly how does the vio client partition gets the virtual ethernet scsi client adapter... (1 Reply)

krb5_rd_error
KRB5_RD_ERROR(3) BSD Library Functions Manual KRB5_RD_ERROR(3)NAME
krb5_rd_error, krb5_free_error, krb5_free_error_contents, krb5_error_from_rd_error -- parse, free and read error from KRB-ERROR message
LIBRARY
Kerberos 5 Library (libkrb5, -lkrb5)
SYNOPSIS
#include <krb5.h>
krb5_error_code
krb5_rd_error(krb5_context context, const krb5_data *msg, KRB_ERROR *result);
void
krb5_free_error(krb5_context context, krb5_error *error);
void
krb5_free_error_contents(krb5_context context, krb5_error *error);
krb5_error_code
krb5_error_from_rd_error(krb5_context context, const krb5_error *error, const krb5_creds *creds);
DESCRIPTION
Usually applications never needs to parse and understand Kerberos error messages since higher level functions will parse and push up the
error in the krb5_context. These functions are described for completeness.
krb5_rd_error() parses and returns the kerboeros error message, the structure should be freed with krb5_free_error_contents() when the caller
is done with the structure.
krb5_free_error() frees the content and the memory region holding the structure iself.
krb5_free_error_contents() free the content of the KRB-ERROR message.
krb5_error_from_rd_error() will parse the error message and set the error buffer in krb5_context to the error string passed back or the
matching error code in the KRB-ERROR message. Caller should pick up the message with krb5_get_error_string(3) (don't forget to free the
returned string with krb5_free_error_string()).
