Top UNIX (Solaris/AIX/HP-UX) Issues/Workarounds/Best Practices for NFS v3/v4.0
This article lists the top known issues, workarounds and best practices for UNIX clients (Solaris/AIX/HP-UX), when used with NetApp FAS controllers running Data ONTAP 7-Mode or clustered Data ONTAP.
Known Issues and Workarounds:
nfs-kerberosfails with the
permission deniederror if
kinitenabled on these clients,
nfs-kerberos authenticationwill fail and displays:
kinit: No supported encryption types (config file error?).
Error=5seen while server SFO/unplaned reboot.
Description: When the server goes through an unplanned SFO or reboot, the client side application might see an
Workaround: For Solaris 11.2 this is fixed in following SRU. Oracle Solaris 220.127.116.11.0 Support Repository Update (Oracle Solaris 11.2 SRU6.4) ( Doc ID 1962769.1 ). For Solaris 10, this if fixed by patch 150401-21.So we need to have patch 150401-21 OR above.
AIX 7.1 TL0 SP4:
nfsv4mount with clustered Data ONTAP fails with the error '
data IP is not in hosts database'.
Description: Mount fails with NFS v4.0 displaying the error '
data IP is not present in host database'.
Workaround: Add data LIF IP in the
/etc/hostsfile on the client to resolve the issue.
HP-UX 11i v3: Creating a directory on the
nfsv4mount might result in permission denied.
Description: Unable to create directories on an NFS v4 mount since the default UID/GID for root user must be 0/0; however, it is in this version of HPUX OS 0/3 (root/sys), so the storage system responds with the error message:
sys entryin the
etc/groupfile on the storage system (Data ONTAP 7-Mode). In the case of clustered Data ONTAP, create Unix-group for sys to resolve the issue.
