Q: Is it possible to configure SNS GlobalSAN and Xtarget with Apple XSAN over iSCSI?
Here is a detailed break down of my setup and step by step -
THE SETUP:
1 x Mac Pro with Xtarget + GlobalSAN iSCSI initiators (Licensed)
3 x iMacs with GlobalSAN iSCSI initiators (trial ENDING 5TH DEC)
All are OSX 10.8 / Mountain Lion Server
XSAN is enabled on all machines
As advised - I have created 2 networks.
With the Mac pro, I have 2 ethernet ports.
With the iMacs, there is only 1 port, so I have duplicated the connection (as per Jason's suggestion)
I have manually configured the IP's so the 2 networks are:
- 192.168.0.* (iSCSI)
- 192.160.20.* (Metadata)
THE XTARGET MACHINE (Mac Pro):
I have placed the startup disk in the second bay beneath the optical drive.
The 4 HDD bays are filled with 2TB WD BLACK drives.
As the drives had been initially formatted, I did "erase free space" on all of the drives as suggested.
This caused one of the drives to fail and prevent boot up, so it's been removed leaving only 3 x 2TB drives.
On the GlobalSAN prefs pane, I have set the following:
UNDER XTARGET TAB:
- Allow incoming iSCSI connections
- Selected the 3 x 2TB drives as LUNs - status 'Online'
UNDER INITIATOR TAB:
- I have selected 'Local Xtarget Server'
- Under connections I have:
- 127.0.0.1 status 'Offline'
I have also added my 2 ethernet connections:
- 192.168.0.4 status 'Online'
- 192.168.20.4 status 'Online'
(.4 is the manually assigned IP for the Xtarget machine)
I have left the rest of the settings as default.
I can see that this mounts the iSCSI drives onto the desktop of the Mac Pro.
MDC1 - iMac
On MDC1 - I have OSX Server installed (Mountain Lion Server)
The GlobalSAN initiator is set to the portal of the Xtarget server.
I can see that this mounts the iSCSI drives onto the desktop of the iMac
XSAN Admin:
- I am able to configure my cluster of machines on as part of a SAN, with 2 iMacs as MDCs, the Xtarget machine and another iMac as clients.
- Once the SAN is created, I am asked if I'd like to create a volume.
- I select the kind of volume I like to create then proceed to the pane the allows me to assign LUNs to affinity tags.
- THIS IS WHERE I GET STUCK -- I cannot see any LUN's visible to assign to any affinity tags.
Is there something that I have missed out or done in error with regards to the process detailed above?
Please advise.
Xsan, OS X Server
