ODM Install

NOTE: If you are configuring AIX with VIOS, please see the IBM VIOS section below for when and where to install the ODM.

1. Zone only one HBA port on AIX to the desired Pure controller port(s).
2. You will only have one hdisk to install on to.
3. Install AIX on hdisk.
4. You will see:

   
   -bash-4.3# lsdev -Cc disk
   hdisk0 Available 00-00-00 SAS Disk Drive
   hdisk1 Available 00-00-00 SAS Disk Drive
   hdisk2 Available 05-00-01 Other FC SCSI Disk Drive

5. You can then install the PURE ODM definition.
6. Reboot, as prompted by the tool.
7. PURE will have replaced the Other FC drive.

   
   -bash-4.3# lsdev -Cc disk
   hdisk0 Available 00-00-00 SAS Disk Drive
   hdisk1 Available 00-00-00 SAS Disk Drive
   hdisk2 Available 05-00-01 PURE MPIO Drive (Fibre)

8. It is possible a SCSI Reservation still exists on the Pure array. Versions prior to AIX 6.1TL7 will need to clear these reservations using their preferred method. For AIX 6.1TL7+ (Including 7.1 and 7.2) run the following to clear the reservation from AIX before proceeding:

   
   bash-4.3# devrsrv -f -c release -l hdisk2
   Device Reservation State Information
   ==================================================
   Device Name : hdisk2
   Device Open On Current Host? : YES
   ODM Reservation Policy : NO RESERVE
   Device Reservation State : NO RESERVE
   Device is currently Open on this host by a process.
   Do you want to continue y/n:y
   The command was successful.
   
   

   Note: There is an IBM issue where the "devrsrv -f -c release -l hdisk1" command fails to clear SCSI-2 reservation see IBM's IV76821 for 6.1 and IV76995 for 7.1.

9. You can now continue adding your subsequent zoned paths and LUN's.
