Figure 5-23 shows that the virtual SCSI adapter in slot 30 is connected to the VIO_Server1 partition. Figure 5-23 LPAR properties window 5. Disable the vscsi0 path for the hdisk0 using the chpath command. # lspath Enabled hdisk0 vscsi0 Enabled hdisk0 vscsi1 # chpath -l hdisk0 -p vscsi0 -s disable paths Changed # lspath Disabled hdisk0 vscsi0 Enabled hdisk0 vscsi1 Now we can start to update the VIO_Server1 partition. 1.

2. On an AIX system with sufficient space, the file fixpack80.tar.gz has been extracted into a new directory via the command # gunzip -dc ../fixpack80.tar.gz | tar -xvf- 3. On the VIO_Server1 partition, a new directory /home/padmin/updates has been created and the contents of the extracted Fix Pack were transmitted using the ftp command from the AIX system to this directory. 4. On the VIO_Server1 partition, to upgrade, we issued the updateios command; the results are shown in Example 5-12.
