Remove the FSPM Software (Optional)

To completely remove the Oracle FS Path Manager (FSPM) software from your system, follow these steps:

If possible, ensure that any Oracle FS System LUNs are not in use by AIX. For example, any volume groups that include a Oracle FS System LUN should be varied off with the varyoffvg command. This is not possible if the system is booted from a Oracle FS System LUN since the boot LUN is in use.
Use facilities such as port masking on the Oracle FS System system, and switch configuration to ensure that there is only one path for each LUN between the host and the Oracle FS System system. This is particularly important for the boot LUN if the system is booted from a Oracle FS System LUN.
Use one of the normal AIX methods to remove the fspm.rte software package.
Example: Choose one of:
- From the command line, enter:
```
installp -ug fspm.rte
```
- From smit (System Management Interface Tool) or smitty (ASCII terminal version of the System Managment Interface Tool):
  1. Go to the Software Installation and Maintenance option.
  2. Select Software Maintenance and Utilities.
  3. Choose Remove Installed Software.
  4. In the Software Name field, enter:
```
fspm.rte
```
Reboot the system.

Note: If the system is currently booted from a Oracle FS System or Pillar Axiom LUN, the following message may be displayed a number of times while the software is being removed:

unable to identify boot disk

This message can safely be ignored.

If any Oracle FS System LUN is busy during the uninstall (which is often true if the system is booted from a Oracle FS System LUN) an error message will be displayed during the uninstall for each busy LUN as follows:

Method error (/usr/lib/methods/ucfgdevice):
        0514-062 Cannot perform the requested function because
                 the specified device is busy.

In this case, after the reboot some configuration commands will cause error messages. For example:

# lsdev -c disk
lsdev: 0514-521 Cannot find information in the predefined device
        configuration database for the customized device hdisk7.
hdisk0  Available 06-08-01-3,0 16 Bit LVD SCSI Disk Drive
hdisk1  Available 06-08-01-4,0 16 Bit LVD SCSI Disk Drive
hdisk6  Available 07-08-02     Other FC SCSI Disk Drive
hdisk7  Defined   07-09-02     N/A
hdisk8  Available 07-08-02     Other FC SCSI Disk Drive

To correct this, simply follow the instructions below to install the FSPM software package again and immediately remove it again. You do not need to make any changes to the SAN configuration.

Important! Do not reboot the host during this sequence.

Follow the steps for installing the FSPM software. Do not reboot the host when instructed to do so.
Follow the steps above to remove the package again. You do not need to reboot the host at the end.

The configuration commands will no longer produce errors. For example:

# lsdev -c disk
hdisk0  Available 06-08-01-3,0 16 Bit LVD SCSI Disk Drive
hdisk1  Available 06-08-01-4,0 16 Bit LVD SCSI Disk Drive
hdisk6  Available 07-08-02     Other FC SCSI Disk Drive
hdisk8  Available 07-08-02     Other FC SCSI Disk Drive
