Connect HP-UX iSCSI to netapp

 

Follow the http://docs.hp.com/en/T1452-90011/index.html
Install iSCSI software initiator on HP-UX.

 

 

Verify under 11.23

 

 

1) # swlist iSCSI-00
# Initializing...

-K: scan the kernel without scanning the real hardware. Drivers that are not bound will also be executed. You can use-D-C-I-H to limit the output at the same time, but you cannot use-u

-U: scans and lists available system I/O devices instead of actually scanning hardware. (The driver and instance number are already in the kernel)

-F: Full List (full field details)

-N: name of the device file in the output. Only some in/dev are listed.

 

 

2. Configure iSCSI software Initiator

 

Path = $ path:/opt/iSCSI/bin

Configure iSCSI initiator Name:

Iscsiutil-l --> some names appear in the column

# Iscsiutil-l
Initiator name: iqn.1986-03.com. HP: db1.679d66a5-5b2e-11db-89e6-08a23597f208

 

3. Configure iSCSI Lun on netapp

Qtree:/vol/vol1/iscsi1

Lun:

Lun show
/Vol/vol1/iscsi1/lun0 10 GB (10737418240) (R/W, online)
/Vol/vol1/iscsi1/lun2
1g (1073741824) (R/W, online, mapped)

Igroup show
Ig0 (iSCSI) (ostype: HPUX ):
Iqn.1986-03.com. HP: db1.679d66a5-5b2e-11db-89e6-08a23597f208

4. Continue with the initiator configuration on HP-UX.

 

 

1) iSCSI target discovered:

 

 

Iscsiutil-a-I 192.168.1.110 ---> default port 3260

Display the iSCSI target

# Iscsiutil-p-d

Discovery target information
----------------------------

Target #1
-----------
IP Address: 192.168.1.110

Iscsi TCP port: 3260
Iscsi portal group Tag: 1

User configured:
----------------

Authenticaton method:
Chap method: chap_uni
Initiator chap Name:
Chap secret:
Header Digest: None, crc32c (default)
Data Digest: None, crc32c (default)

 

 

2) discover operable target devices

 

# Ioscan-H 255

In this case, no new device is found. The target already exists. The iSCSI Lun and group settings on the netapp should be correct. The problem may still occur on the network.

Netapp has multiple interfaces, one of which is an external outlet (1.110, the default gateway is also added to this interface). Others are internal product interfaces, which are different.
Vlan5, 6, 7, and 8. The HP-UX is a testing machine, which belongs to the product vlan14, but is not in the scope of the netapp interface. Therefore, what is HP-UX used to connect to netapp?
External egress, but the firewall limits the connection between this interface and the internal (outbound. However, the default route VLAN and the HP-
UX does not exist, so

 

Add a route to netapp. # route add host 192.168.14.221 (HP-ux ip) gateway IP address of vlan7

Then reset the target and query

Iscsiutil-a-I 192.168.7.110

After verifying iscsiutil-p-D, confirm the new target

Try again to find the new device ioscan-H 255

In fact, all disks point to a real physical disk, but there are only multiple paths.

? How does one correspond to the previously discovered iSCSI (that is, how to control which netapp IP resource to use )? 6 <---> 5
