AIX Host Installation/Upgrade Procedures
If the earlier architecture decision concerning the access LUN mapping versus
removal of software packages devices.fcp.disk.array.* was to not
remove the software packages and to remove the mapping of the access
LUNs, thereby not being able to see the access LUNs, skip this section.
This section is run regardless of whether you’re using a failover or non-failover
solution.
1. mkdir /usr/lpp/stkfc
2. cd /usr/lpp/stkfc
3. ftp the file access.tar from the CRC site into the current directory.
4. untar the file.
tar xvf access.tar
5. install the odm entries using:
./install_access
Note: If the Cambex failover driver is removed or upgraded, this
procedure must be rerun because the Cambex removal process
removes the above ODM entries.
Installing Compatibility Software
There are three installation packages (stk.svadisk, stk.renumber, stk.hacmp)
available on the Cambex DPF Failover CD or on the CRC site in the file
compatibility.tar . The next steps will transfer the packages onto the host.
1. mkdir /usr/lpp/stkfc
2. cd /usr/lpp/stkfc
3. ftp the file compatibility.tar from the CRC site or copy off of the CD into the
current directory.
4. untar the file.
tar xvf compatibility.tar
The stk.svadisk package changes the set of attributes of disks on SVAs (V2X/
V2X2, V960, or 9500) to optimize the disk I/O performance. This package is
required for the installation of the stk.renumber package.
The stk.renumber package resolves the ghost disk problem that occurs when
multiple AIX servers see the same set of disks.
The stk.hacmp package helps notify the user when the Cambex DPF failover
software detects FC error conditions and triggers HACMP node failover when
the DPF driver detects the “all paths bad” to a volume(s).
The software packages need to be installed in the following order.
