AIX systems

Procedure

Determine the Fibre Channel port address that you must use for the host definition on the disk subsystem. Issue the lscfg command for every port.

On small and medium systems, issue the following commands:

lscfg -vps -l fcs0 | grep "Network Address"
lscfg -vps -l fcs1 | grep "Network Address"

On large systems, issue the following commands:

lscfg -vps -l fcs0 | grep "Network Address"
lscfg -vps -l fcs1 | grep "Network Address"
lscfg -vps -l fcs2 | grep "Network Address"
lscfg -vps -l fcs3 | grep "Network Address"

Ensure that the following AIX® file sets are installed:
- devices.common.IBM.mpio.rte
- devices.fcp.disk.rte
Issue the cfgmgr command to have AIX rescan the hardware and discover available disks. For example:
```
cfgmgr
```

To list the available disks, issue the following command:

lsdev -Ccdisk

The output is similar to the following example:

hdisk0  Available 00-00-00 SAS Disk Drive
hdisk1  Available 00-00-00 SAS Disk Drive
hdisk2  Available 01-00-00 SAS Disk Drive
hdisk3  Available 01-00-00 SAS Disk Drive
hdisk4  Available 06-01-02 MPIO IBM 2076 FC Disk
hdisk5  Available 07-01-02 MPIO IBM 2076 FC Disk
...

Use the output from the lsdev command to identify and list device IDs for each disk device.

For example, a device ID could be hdisk4. Save the list of device IDs to use when you create file systems for the IBM Storage Protect server.
Correlate the SCSI device IDs to specific disk LUNs from the disk system by listing detailed information about all physical volumes in the system. Issue the following command:
```
lspv -u
```
On an IBM® Storwize® system, the following information is an example of what is shown for each device:
```
hdisk4  00f8cf083fd97327  None  active     
 332136005076300810105780000000000003004214503IBMfcp
```
In the example, 60050763008101057800000000000030 is the UID for the volume, as reported by the Storwize management interface.
To verify disk size in megabytes and compare the value with what is listed for the system, issue the following command:
```
bootinfo -s hdisk4
```
