iSCSI
Initiator config
Kernel Update Needed
The current kernel does not support iSCSI transport.
The current kernel does not support iSCSI transport.
Host is OpenRD
- Install the iscsi-initiator-utils package.
- Placed "InitiatorName=iqn.2000-10.ca.on.senecac.hongkong" in /etc/iscsi/initiatorname.iscsi
- Start the iscsi and iscsid services.
- Discover the remote targets: iscsiadm -m discovery -t sendtargets -p hongkong:3260
- List the targets: iscsiadm -m node -- the remote target(s) should be shown.
- Login to the targets: iscsiadm -m node -l
- You will now have an additional scsi disk device. Use this as one element of a RAID-1 array, using local storage (an LV or a looped-back file) as the other element.
- Mount the new RAID-1 array and create a filesystem on it. Place some files there.
- Unmount the filesystem, stop the array, log out of the iSCSI disk (iscsiadm -m node -u).
- Verify that the filesystem can be locally read on the machine hosting the target.
PATA/USB Config
- PATA drive connected via USB
- Device is /dev/sda1 if no other storage is connected
Target Config
- Host is HongKong
- IQN is "InitiatorName=iqn.2000-10.ca.on.senecac.hongkong"
- Target is "target0" which is connected to the LV HongKong/arm1iscsi, size 2GB
