Affected Component | Description |

|
All UNIX and Linux | In a file system configuration file, if the Metadata parameter for a stripe group |
| was set to Yes when the file system was created, do not later change the |
| parameter to No. Doing so will cause the metadata to become inaccessible and |
| result in errors. Also, if the parameter is changed to No, the cvupdatefs |
| command might allow bandwidth expansion of the stripe group, resulting in |
| metadata corruption. |
|
|
Solaris | On Solaris, by default, the /usr/lib/fs/nfs/nfsfind script is run nightly by the |
| cron daemon. This script contains a find command that traverses any local file |
| system that is exported (shared) via NFS. If the running of this script is |
| interfering with the performance of processes accessing StorNext file |
| systems, it can be modified to skip them. To do so, add the following line to |
| the find command in the script: |
| '(' |
| The final find command should look like this: |
| find $dir '(' |
| rm |
|
|
| The Solaris Security Toolkit, formally known as JASS, causes the following |
| two issues: |
| • It disables RPC by renaming the RPC startup script, disrupting the |
| StorNext interprocess communication. To fix the communication problem, |
| rename the RPC startup script in /etc/init.d from rpc.<illegal extension> to rpc. |
| • It turns on IPSec, causing numerous warning messages in the system log |
| file. Either disable IPSec by removing the IPSec startup file in /etc/init.d or |
| contact Sun Technical Support to find out how to reconfigure IPSec to |
| ignore local loopback connections. |
|
|
Windows | Windows Services for UNIX (SFU) supports only NTFS for NFS exports. |
| Because of this limitation, a Windows system cannot act as an NFS server for |
| StorNext File System. |
|
|
| When a StorNext file system is mounted to a drive letter or a directory, |
| configure the Windows backup utility to NOT include the StorNext file |
| system. |
