iqn.[servername].[iscsidiskname]
• The format of IQN names for VSS-based iSCSI disks on the SnapServer is:
iqn.1997-10.com.snapserver:[servername]:[diskname].[nnn]
where [servername] is the name of the SnapServer, [diskname] is the name of the
iSCSI disk on the target SnapServer, and [nnn] is a sequential number starting
from 000. For example:
iqn.1997-10.com.snapserver:snap123456:iscsi0.000
• The format of IQN names for VDS-based iSCSI disks on the SnapServer is:
iqn.1997-10.com.snapserver:[servername]:[diskname]-snap[n]
where [servername] is the name of the SnapServer, [diskname] is the name of the
iSCSI disk on the target SnapServer, and [n] is a sequential number starting from
0. For example:
iqn.1997-10.com.snapserver:snap123456:iscsi0-snap0
Creating iSCSI Disks
Navigate to Storage > iSCSI to to create, edit, or delete iSCSI Disks on the
SnapServer. Be sure to read “iSCSI Configuration on the SnapServer” on page 88
before you begin creating iSCSI Disks.
Note You cannot delete or edit an iSCSI disk until all clients have been
disconnected from that disk.
Click
VSS/VDS Access to add VSS/VDS clients to the SnapServer. See “Configuring
VSS/VDS for iSCSI Disks” on page 93 for more information.
To use CHAP authentication
1 Click to put a check in the Enable CHAP Logon box.
2 Enter a user name and target secret (password). Both are case sensitive.
• The user name range is 1 to 223 alphanumeric characters.
• The target secret must be a minimum of 12 and a maximum of 16 characters.
GuardianOS Support for CHAP Security (Target Only)
CHAP is a network login protocol that uses a challenge-response mechanism to
control iSCSI initiator access to an iSCSI target. GuardianOS supports target
authentication, in which the initiator must provide the same CHAP user name and
password (or "target secret") that was configured on the target SnapServer iSCSI
disk. Other forms of CHAP authentication are not currently supported.
