22 Using the CLI
Size representations
Parameters such as names of users and volumes have a maximum length in bytes. ASCII characters are 1
byte; most Latin (Western European) characters with diacritics are 2 bytes; most Asian characters are 3
bytes.
Operating systems usually show volume size in base 2. Disk drives usually show size in base 10. Memory
(RAM and ROM) size is always shown in base 2.
In the CLI, the base for entry and display of storage-space sizes can be set per user or per session; see
create user and set cli-parameters. When entering storage-space sizes only, either base-2 or base-10 units
can be specified.
The locale setting determines the character used for the decimal (radix) point, as shown below.
Event log
A controller enclosure’s event log records all events that have occurred in or been detected by the controller
modules and encompasses all field-replaceable units (FRUs) in the storage system.
Each event has one of the following levels, in decreasing severity:
• Critical. A failure occurred that may cause a controller to shut down. Correct the problem immediately.
• Error. A failure occurred that may affect data integrity or system stability. Correct the problem as soon
as possible.
• Warning. A problem occurred that may affect system stability but not data integrity. Evaluate the
problem and correct it if necessary.
• Informational. A configuration or state change occurred, or a problem occurred that the system
corrected. No action is required.
For information about viewing events, see the show events command.
