Low memory and disk warnings
If the amount of memory or disk space is low, the following messages are output on the
systems.
WARNING: LOW MEMORY WARNING: LOW DISK WARNING: LOW MEMORY/DISK
Note:
The LOW DISK messages are not displayed after sysload and until a data dump is
performed.
Warning:
When the LOW MEMORY, LOW DISK, or LOW MEMORY/DISK messages appear, avoid
performing further administration changes which require more memory and disk space.
These changes can be lost during the next data dump.
When low memory or disk problems occur, a review of system memory is recommended.
Memory can be reclaimed by removing unused features. For example, the system may have
speed call lists which are no longer used and can be removed.
Depending on the data storage type required (such as protected/ unprotected), it can be
necessary to perform an initialize or sysload to access the reclaimed data store space.
A disk record stores approximately 500 words of protected data store. A single 3.5 inch high
density floppy disk can hold a maximum of 1425 records.
When the software detects that more than one floppy disk is required, the data is compressed
during the backup, thereby reducing the number of disks required.
System Lookup messages
On systems equipped with System Errors and Events Lookup package 245, it is possible to
display system messages on screen. Specific system messages may then be viewed on
screen if the user enters ERR followed by the desired system error code and . The
following example shows the data entries necessary to view error message SCH946:
• Login to switch
• PASS (Enter only your password)
• ERR SCH946(The user must type "ERR SCH946" and press return)
The screen displays the error message corresponding to SCH946. In this case, that message
is:
Invalid User Type
