8.5 Resolving Problems When Only Some
Volumes Mount
To diagnose problems when only some volumes mount, identify whether the following conditions
exist:
exist:
The server does not have enough RAM.
The disk drivers for external drives are not loaded.
To resolve problems when only some volumes mount, do the following:
Add more RAM.
Verify which drivers are loaded.
8.6 Resolving Disk Error Problems When a
Volume is Mounting
To diagnose problems when disk errors occur while a Traditional volume is mounting, identify
whether the following conditions exist:
whether the following conditions exist:
The server does not have enough memory to mount the volume.
The operating system is experiencing directory sector mismatching. This mismatching can be
caused if the media is defective or if the server is turned off without the Down command.
caused if the media is defective or if the server is turned off without the Down command.
To resolve disk error problems that occur while a volume is mounting:
Check the status of the available cache buffers. If the available cache buffers are fewer than
20%, add more memory to your server.
20%, add more memory to your server.
Minor errors usually correct themselves through normal network use. For example, if a FAT
entry is wrong, the entry is updated and corrected the next time the table is written to. If errors
do not correct themselves, repair the volume using the Vrepair utility.

8.7 Resolving Memory Errors When a Volume Is
Mounting
To diagnose memory error problems when a Traditional volume mounts, identify whether the
following conditions exist:
following conditions exist:
Volumes take more memory to mount than they require after being mounted because the
mounting process performs consistency checks (for example, the duplicate copies of all the
tables are checked).
mounting process performs consistency checks (for example, the duplicate copies of all the
tables are checked).
Volumes and directory entries grow dynamically. Therefore, if your server is using most of the
RAM (file cache buffers are close to 20% of the memory) and you dismount a volume, you
might not be able to remount the volume unless additional memory is available.

might not be able to remount the volume unless additional memory is available.
Each additional name space support that you add to a volume increases the size of the file
allocation tables and directory entry tables. Adding name space support can cause the tables to
grow so large that the server does not have enough RAM to mount the volume.
