This behavior is a result of the unusually high sustained data rate in the cut-and-paste operation. You can avoid this issue by using an SSH console session instead of accessing the system console through the RLM or SP. IBM System Storage N series: Data ONTAP 8.0.4 7-Mode Release Notes...
Page 99: Ntp Version Used To Communicate With A Newly Configured Ntp Server Defaults To V3
NTP version used to communicate with a newly configured NTP server defaults to v3 Starting with Data ONTAP 8.0.2, the Network Time Protocol (NTP) version to be used for communicating with a newly configured NTP server defaults to v3 instead of v4. This change is to address situations where certain time servers support only NTP v3.

If the system is running a heavy load or if the network is slow, the AutoSupport message might not be delivered. However, EMS messages report that thresholds have been crossed, regardless of whether an AutoSupport message is delivered. IBM System Storage N series: Data ONTAP 8.0.4 7-Mode Release Notes...
Page 101: Storage Resource Management Issues
Storage resource management issues If you have more than one size of disk installed in your storage system, if you have configured quotas or if you use FlexCache volumes you should familiarize yourself with these storage resource management issues. For more information about these issues, see the Data ONTAP 8.0 7-Mode Storage Management Guide.
Page 102: Data Ontap Can Silently Select Varying Disk Sizes Or Array Lun Sizes When Creating An Aggregate
To specify the disk size when you add a disk to an aggregate, enter the following command: aggr add aggr_name num_disks@size Example For example, to add four 635-GB disks to aggr1, enter the following command: IBM System Storage N series: Data ONTAP 8.0.4 7-Mode Release Notes...
Page 103: Discovering What Disks Data Ontap Will Automatically Select
aggr add aggr1 4@635G Discovering what disks Data ONTAP will automatically select To list which disks would be selected, use the -n option for the aggr create or aggr add command. When you use the -n option, the disks that would be selected automatically, if you created an aggregate or added to an aggregate, are displayed.
Page 104: High-Availability Pair Issues
If you are using HA pairs, you might need to familiarize yourself with these issues.

Page 107: Value Of The Option Nfs.ifc.rcv.high Is Unexpectedly Reset
Value of the option nfs.ifc.rcv.high is unexpectedly reset The option nfs.ifc.rcv.high value might unexpectedly get reset to a previous value if it is changed by the option nfs.tcp.recvwindowsize. The option nfs.ifc.rcv.high controls the high-water mark after which NFS level flow control takes effect. This option is also controlled by the option nfs.tcp.recvwindowsize.
Page 108: File Copy Operation On A Widelink Path Inside A Cifs Share Might Fail When Using Smb 2.X
Controlling NFS requests from nonreserved ports You can reject NFS mount requests from nonreserved ports by enabling the nfs.mount_rootonly option. To reject all NFS requests from nonreserved ports, you can enable the nfs.nfs_rootonly option. IBM System Storage N series: Data ONTAP 8.0.4 7-Mode Release Notes...

Page 111: Too Many Cifs Audit Files Can Cause System Performance Degradation
v Use the cifs prefdc add command to add the writable domain controller to the list of preferred domain controllers on the storage system. For information about the cifs prefdc add command, see the Data ONTAP 8.0 7-Mode File Access and Protocols Management Guide. Too many CIFS audit files can cause system performance degradation If the option cifs.audit.autosave.file.limit is set to 0, it allows an unlimited number of log files to be saved in the /etc/log directory.
Page 112: Excessive Pending Cifs Authentication Requests Can Cause Service Disruption
If the nfs.mount_rootonly option is set to on, Data ONTAP does not allow NFS clients that use nonreserved ports (that is, ports with numbers higher than 1023) to mount the NFS shares. IBM System Storage N series: Data ONTAP 8.0.4 7-Mode Release Notes...
Page 113: Widelinks Are Not Accessible From Mac Clients
Widelinks are not accessible from Mac clients When a user attempts to connect to a share using widelinks from a Mac OS X client, the attempt fails. Widelinks are not accessible from Mac OS X clients. Empty CIFS/SMB2.x change notifications CIFS/SMB2.x clients connected to the storage system might request to be notified about changes to a particular directory.
Page 114: Block Access Protocol Issues
If your storage systems are part of a SAN environment, you might need to familiarize yourself with block access protocol issues in this release. For more information about these issues, see the IBM System Storage N series Data ONTAP 8.0 7-Mode Block Access Management Guide for iSCSI and FC.
Page 115: If An Iscsi Target Hba Fails
If an iSCSI target HBA fails If your iSCSI target host bus adapter (HBA) fails, the iSCSI initiators connected to this HBA might time out, prompting the following error message on the storage system: iSNAP.fw.Crashed The timeout on the iSCSI initiators might be caused by HBA firmware defects, hardware failure, or device driver defects.

SCC device assigned to LUN 0 must also be mapped to a DataFort Cryptainer. This enables the storage system to detect LUN 0 and also the SCSI devices attached to it. IBM System Storage N series: Data ONTAP 8.0.4 7-Mode Release Notes...
Page 117: Tape Backup And Volume Move Operations Must Not Be Performed Simultaneously
Tape backup and volume move operations must not be performed simultaneously You must not perform a tape backup or restore operation while a volume move operation is in cutover phase. Similarly, you must not perform a volume move operation while a tape backup or restore is in progress. You should wait until one of the operations is complete before initiating the other.
Page 118: Restore Engine Does Not Honor Any Mandatory Or Advisory Locks On Files
When you initiate a restore operation to such a volume, the restore engine does not honor these locks. It ignores these locks and overwrites the files. IBM System Storage N series: Data ONTAP 8.0.4 7-Mode Release Notes...
Page 119: Restore Operation To A Non-Existent Volume Restores Data To The Root Volume
Restore operation to a non-existent volume restores data to the root volume If the destination of your restore operation is a non-existent volume, data is restored to the root volume. Suboptimal space savings with deduplication when 16-GB Performance Acceleration Module is installed When you run a deduplication scan by using the sis start -s command on a volume with existing data and with the 16-GB Performance Acceleration Module installed, you obtain suboptimal space savings.
