Change In The Frequency Of The Performance Autosupport Message; Use Flexshare With Hdds Only; Correction To The Free Space Required For Reallocation Scans; Changes To The Supported Openssh Client Versions - IBM N Series Manual

Change in the frequency of the performance AutoSupport message

Starting from Data ONTAP 8.0.3, an AutoSupport message is sent when the
cm_hourly_stats file reaches the threshold limit. Therefore, it is possible that
the performance AutoSupport message might be sent more than once a week.

Use FlexShare with HDDs only

Use FlexShare with storage systems that have hard disk drives (HDDs) only.
FlexShare is not designed for use with storage systems that have solid-state
drives (SSDs). Enabling FlexShare on a storage system that has SSDs can
result in decreased throughput to SSD-based volumes.

Correction to the free space required for reallocation scans

The topic "What a reallocation scan is" includes incorrect information.
The following content is incorrect:
Reallocation scans will not run if there is less than 10 percent free space
(excluding the Snapshot reserve) in the active file system on the target volume
or aggregate.
The content is corrected as follows:
Reallocation scans will not run if there is less than five percent free space
(excluding the Snapshot reserve) in the active file system on the target volume
or aggregate.

Changes to the supported OpenSSH client versions

The SSH protocol section of the Data ONTAP 8.0 7-Mode System Administration
Guide has updated information for OpenSSH client versions that Data ONTAP
supports.
Data ONTAP supports the following SSH clients:
v OpenSSH client version 4.4p1 on UNIX platforms
v SSH Communications Security client (SSH Tectia client) version 6.0.0 on
Windows platforms
v Vandyke SecureCRT version 6.0.1 on Windows platforms
v PuTTY version 0.6.0 on Windows platforms
v F-Secure SSH client version 7.0.0 on UNIX platforms
To enhance security, OpenSSH client version 3.8p1 is no longer supported
because it does not contain the latest security fix.

Changes to storage system configuration backup and restore

The Data ONTAP 8.0 7-Mode System Administration Guide has updated
