Table 70 Server connection permission levels
Allows This Type of Access
Prevents the server from accessing the volume or snapshot. No access
Restricts the server to read-only access to the data on the volume or snapshot. Read access
Allows the server read and write permissions to the volume. Read/write access
NOTE: Microsoft Windows requires read/write access to volumes.
Assigning server iSCSI connections from a volume
You can assign one or more server connections to any volume or snapshot.
1. In the navigation window, right-click the volume you want to assign server connections to.
2. Select Assign and Unassign Servers.
3. Select the Assigned check box for each server connection you want to assign to the volume
or snapshot.
4. From the Permission list, select the permission each server connection should have to the volume
or snapshot.
5. Click OK.
You can now log on to the volume from the server’s iSCSI initiator. See “Completing the iSCSI
Initiator and disk setup” (page 203) .
Assigning volumes from an iSCSI connection
You can assign one or more volumes or snapshots to any server connection.
1. In the navigation window, right-click the server connection you want to assign.
2. Select Assign and Unassign Volumes and Snapshots.
3. Select the Assigned check box for each volume or snapshot you want to assign to the server
connection.
4. From the Permission list, select the permission the server should have.
5. Click OK.
You can now connect to the volume from the server’s iSCSI initiator. See “Completing the
iSCSI Initiator and disk setup” (page 203) .
Assigning volumes to Fibre Channel servers
After configuring the Fibre Channel servers in the CMC, you assign LUNs to the servers. You can
make the assignments in either of two ways:
•
“Assigning Fibre Channel servers from a volume” (page 210)
•
“Assigning volumes from a Fibre Channel server” (page 210)
Prerequisites
•
The server connections you want to assign must already exist in the management group. See
“Adding a Fibre Channel server connection” (page 204) .
•
The volumes or snapshots you want to assign must already exist in the management group.
•
To prevent a LUN conflict, if a volume or snapshot is assigned to more than one Fibre Channel
server, it must have the same LUN assigned for each server.
•
When planning LUN assignments for Windows Servers using Fibre Channel, the LUNs must
be numbered from 1 to 254. HP StoreVirtual Storage does not support using LUN 0 with Fibre
Channel. The maximum number of LUNs supported by Windows is 255 LUNs per target, with
an ID range of 0 to 254. Consequently, LUN 255 is not supported either.
