Troubleshooting a SAN File System client

This topic provides an overview of how to resolve problems with SAN File System clients.

SAN File System clients run the following operating systems:
  • AIX® 5.1 (32–bit only) – maintenance level 3 or higher
  • AIX 5.2 (32-bit and 64-bit)
  • Red Hat Enterprise Linux Advanced Server 3.0
  • Sun Solaris 9 (64-bit)
  • Windows® 2000 Server or Advanced Server – minimum Service Pack 4
The Flexible SAN environment can be set up to allow clients to access only the storage pools assigned to it. Otherwise, all of the clients can be set up to access the same global namespace. File permissions are based on the operating system on which the files were created. The security features of the operating system on which the file was created are available and enforced. Across platforms, the following security rules apply:
  • When files created by an AIX client are accessed by a Windows client, access is controlled by the permissions of the Other permission bits.
  • When files created by a Windows client are accessed by an AIX client, access is controlled by the permissions of the Everyone group.
  • When files created by a Linux client are accessed by a Windows client, access is controlled by the permissions of the Other permission bits.
  • When files created by a Windows client are accessed by a Linux client, access is controlled by the permissions of the Everyone group.
  • When files created by a Solaris client are accessed by a Windows client, access is controlled by the permissions of the Other permission bits.
  • When files created by a Windows client are accessed by a Solaris client, access is controlled by the permissions of the Everyone group.
