Dependent Subsystems

• Underlying Filesystems –

VxFS, HFS, CDFS, LOFS

• Commands – mount,

umount, bdf, df, ls, etc.

• Libraries – libc,

libpthread, etc.

• Buffer Cache

• Kernel Bubble

• LAN Common

• Network Link Specific –

Ethernet, Gigabit, Token

Ring, ATM, etc.

• Network Transport

• SAM

patching

It is very important to keep the patch levels of all the underlying subsystems (i.e.

network, buffer cache, transport, etc.) current since a defect in those subsystems

can negatively impact NFS behavior and performance.
