Installing iSCSI on AIX 5.2
To install iSCSI on AIX 5.2 ML3, follow these steps: 1. Verify the Maintenance level server is running: # oslevel -r 5200-03
2. Verify the correct iSCSI FileSets have been installed: # lslpp -l | grep -i iscsi
devices.common.IBM.iscsi.rte
5.2.0.30 COMMITTED Common iSCSI Files
devices.iscsi.disk.rte 5.2.0.30 COMMITTED iSCSI Disk Software
devices.iscsi.tape.rte 5.2.0.0 COMMITTED iSCSI Tape Software
devices.iscsi_sw.rte 5.2.0.1 COMMITTED iSCSI Software Device Driver
devices.iscsi_sw.rte 5.2.0.1 COMMITTED iSCSI Software Device Driver
3. Verify the iSCSI nodename on the filer: filer> iscsi nodename iSCSI target nodename:
iqn.1992-08.com.netapp:sn.33580086
4. Add the IP Address, default iSCSI port number, and iSCSI NodeName of the filer:
# tail -2 /etc/iscsi/targets
10.00.000.188 3260 iqn.1992-08.com.netapp:sn.33580086 5. Verify the iSCSI device is available in the kernel: # lsdev -C | grep iscsi
iscsi0 Available iSCSI Protocol Device 6. Verify the iSCSI nodename of the AIX server: # lsattr -El iscsi0
disc_filename /etc/iscsi/targets Configuration file False
disc_policy file Discovery Policy True
initiator_name iqn.hostid.0a3cc1dc i
SCSI Initiator Name True
max_targets 16 Maximum Targets Allowed True num_cmd_elems 200 Maximum number of commands to queue to driver True
7. Modify the iSCSI nodename of the AIX server:
Note:
AIX's default initiator nodename does not fully comply with RFC and filer nodename requirements. A sample example is given below: #lsattr -El iscsi0
nodename.iqn.aixhost1.hostid.0a3cac46
Change the default initiator nodename to include a date in the second field:
iqn.yyyy-mm.hostname.hostid.0a3cac46
Use the following to change the nodename: chdev -l iscsi0 -a
initiator_name=iqn.1996-04.aixhost1.hostid.0a3cac46
For this example it will be as shown below: # chdev -l iscsi0 -a
initiator_name=iqn.1992-08.com.ibm:aix-rtp.0a3cc1dc iscsi0 changed
8. Verify the AIX server is logging into the filer:
filer> Wed Jun 9 14:40:57 EDT [iscsi.notice:notice]: ISCSI: iswta, New session from initiator
iqn.1992-08.com.ibm:aix-rtp.0a3cc1dc at IP addr 10.00.00.00 9. Create an iSCSI igroup on the filer that contains the iSCSI nodename of the AIX server: filer> igroup create -i aix
iqn.1992-08.com.ibm:aix-rtp.0a3cc1dc
where is the AIX initiator's nodename 10.Create some LUNs on the filer:filer> lun create -s 1g /vol/test/aix.lun filer> lun create -s 1g /vol/test/aix_5L.lun
11.Map the LUNs to the igroup for the AIX server: filer > lun map
/vol/test/aix.lun com.ibm:aix-rtp-iscsi lun map: auto-assigned com.ibm:aix-rtp-iscsi=1
Verify that the LUNs are mapped:
filer> lun show -g aix /vol/test/aix.lun 1g (1073741824) (r/w, online, mapped) /vol/test/aix_5L.lun 1g (1073741824) (r/w, online, mapped) This causes AIX to rescan and log into the filer. $ cfgmgr -v
12.Verify that the block devices have not been created for you on the AIX server:
# lsdev -Cc disk
hdisk0 Available 10-60-00-9,0 16 Bit SCSI Disk Drive hdisk1 Available 10-60-00-8,0 16 Bit LVD SCSI Disk Drive 13.Rescan the iSCSI subsystem for new devices: # cfgmgr -l iscsi0
14.Verify that the block devices have been created for you on the AIX server: # lsdev -Cc disk
hdisk0 Available 10-60-00-9,0 16 Bit SCSI Disk Drive hdisk1 Available 10-60-00-8,0 16 Bit LVD SCSI Disk Drive hdisk2 Available Other iSCSI Disk Drive hdisk3 Available Other iSCSI Disk Drive
