Setting Up a Unix Host to Use iSCSI Storage

                              smit installp
                            

                              uncompress EMC.AIX.x.x.x.x.tar.z
     			tar -xvf EMC.AIX.x.x.x.x.tar
                            

                              smit
                            

                              {portal} {port} {target_iqn}
                            

where:

• {portal} = IP address of the network portal
• {port} = number of the TCP listening port (default is 3260)
• {target_iqn} = formal iSCSI name of the target

                              lsdev -Cc disk | grep “Other FC SCSI Disk Drive” | awk {‘print $1’} | xargs -n1 rmdev -dl
                            

                              installp -u EMC.CLARiiON.*
                            

                              PATH=$PATH:/opt/iscsi/bin
                            

                              iscsiutil -1
                            

The iSCSI software initiator configures a default initiator name in an iSCSI Qualified Name (IQN) format.

For example:

                              iqn.1986-03.com.hp:hpfcs214.2000853943
                            

To change the default iSCSI initiator name or reconfigure the name to an IEEE EUI-64 (EUI) format, continue to the next step; otherwise skip to step 5.

                              iscsiutil [iscsi-device-file] -i -N iscsi-initiator-name
                            

Note:  For mor information on IQN and EUI formats, refer to the HP-UX iscsi software initiator guide.

where:

• iscsi-device-file is the iSCSI device path, /dev/iscsi, and is optional if you include the -i or -N switches in the command.
• -i configures the iSCSI initiator information.
• -N is the initiator name. When preceded by the -i switch, it requires the iSCSI initiator name. The first 256 characters of the name string are stored in the iSCSI persistent information.
• iscsi-initiator-name is the initiator name you have chosen, in IQN or EUI format.

                              iscsiutil -1
                            

                              iscsitutil [/dev/iscsi] -a -I ip-address/hostname [-P tcp-port] [-M portal-grp-tag]

                            

where

• -a adds a discovery target address into iSCSI persistent information. You can add discovery target addresses only with this option.
• -I requires the IP address or hostname of the discovery target address.
• ip-address/hostname is the IP address or host name component of the target network portal.
• -P tcp-port is the listening TCP port component of the discovery target network portal (optional). The default iSCSI TCP port number is 3260.
• -M portal-grp-tag is the target portal group tag (optional). The default target portal group tag for discovery targets is 1.

For example:

                              iscsiutil -a -I 192.1.1.110
                            

or, if you specify the hostname,

                              iscsiutil -a -I target.hp.com
                            

If an iSCSI TCP port used by the discovery target is different than the default iSCSI port of 3260, you must specify the default TCP port used by the discovery target, for example,

                              iscsiutil -a -I 192.1.1.110 -P 5001
                            

or

                              iscsiutil -a -I target.hp.com -P 5001
                            

                              iscsiutil -p -D
                            

                              /usr/sbin/ioscan -H 225
ioscan -NfC disk (for HP-UX 11i v3 only)
                            

                              /usr/sbin/insf -H 225
                            

                              iscsiutil -p -O
                            

                              ioscan -NfC disk|
insf -e
                            

                              ioscan -NfnC disk
                            

                              ioscan -NkfnC lunpath
                            

Use the iscsiadm command to do the following:

For optional initiator CHAP:

1. Enable CHAP as the authentication method.
2. Set the username for the initiator to the initiator’s IQN, which you can find with the iscsiadm -m node command.
3. Set the secret (password) for the initiator to the same secret that you entered for the host initiator on the storage system.

For optional mutual CHAP

1. Set the username (username_in) to the initiator’s IQN, which you can find with the iscsiadm -m node command.
2. Set the secret (password_in) for the target to the same secret that you entered for the iSCSI interface.

Use the YaST to do the following for the open-iscsi driver initiator:

For optional initiator CHAP:

1. Enable incoming authentication.
2. Set the initiator CHAP username to the initiator’s IQN, which you can find with the iscsiadm -m node command.
3. Set the initiator CHAP password (secret) to the same secret that you entered for the host initiator on the storage system.

For mutual CHAP:

1. Enable outgoing authentication (mutual CHAP).
2. Set the mutual CHAP username to the initiator’s IQN, which you can find with the iscsiadm -m node command.
3. Set the initiator password (secret) for the target to the same secret that you entered for the iSCSI interface.

• Edit the /kernel/drv/fp.conf file by changing the mpxio-disable option from yes to no.

  or

• Execute the following command:

                                    stmsboot -e
                                  

                              share -F nfs -d ‘root on target_host‘ -o ro,rw=installer host,root=installer_host /
                            

                              setting load-balance=”round-robin”
                            

                              iscsiadm modify discovery-address 10.14.111.222:3260
                            

Note:  If you do not want the host to see specific targets, use the static discovery method as described in the Solaris server documentation.

                              iscsiadm modify discovery --sendtargets enable
                            

or

                              iscsiadm modify discovery -t enable
                            

                              devfsadm -i iscsi
                            

                              iscsiadm modify target-param -c <logins> <target_iqn>
                            

where logins is the number of logins and target_iqn is the IQN of the iSCSI interface (target).

Note:  You can determine the IQN of the iSCSI interface from Unisphere on the iSCSI Interfaces page ( Storage > Block > iSCSI Interfaces.).
