Appendix

Securing data on an iSCSI SAN—To help secure data transfers between the
server and the subsystem, configure security for the login sessions between
Initiators and Targets. Using Storage Manager for SANs, you can configure
one-way or mutual Challenge Handshake Authentication Protocol (CHAP)
authentication between the Initiator and Targets, and you can also configure
Internet Protocol security (IPsec) data encryption.
NOTE:
It is recommended that you use CHAP if the iSCSI traffic uses the
public network.
Known Issues
• Event generated while dismounting a virtual disk—When you dismount a
locally mounted virtual disk, the following event may be generated in the
system log:
Plugplaymanager 12 event:
The device 'MSFT 00000000F852A09D SCSI Disk
Device'
(SCSI\Disk&Ven_MSFT&Prod_00000000F852A09D\1&2afd7
d61&3&000003) disappeared from the system without
first being prepared for removal.
It is safe to ignore these events for normal
Microsoft iSCSI Software Target dismount
operations.
• Rollback operations on a locally mounted virtual disk—When you mount
a virtual disk locally in read/write mode, any rollback operation performed
on that virtual disk takes a long time to complete.
• Termination of rollback—Disabling a virtual disk during a rollback
terminates the rollback operation without a warning. An event is logged
documenting that the rollback was ended.
• Locally mounted virtual disks are listed in available drives—When you
create a new virtual disk, the locally mounted virtual disks are displayed in
the list of available volumes to host the new virtual disk. A locally mounted
virtual disk does not support storing a virtual disk. If you attempt to select
the locally mounted virtual disk as the storage location for the new virtual
disk, the following error message is displayed:
