asynchronous command, reset the error information in the storage system
using the
raidcom reset command_status
command. You can check the
information in SSB1 and SSB2 by using the
raidcom get error_message
command.
In asynchronous command processing, multiple commands received by the
host are executed at the same time. Therefore, the total number of errors
might not correspond with the unexecuted commands. If an error occurs in
asynchronous commands, verify the system configuration using the reference
commands. For details about the reference commands, see Available
provisioning operations on page 5-6 .
Workflow for executing asynchronous commands
When executing asynchronous commands, execute the command or script
using the following procedure:
1
.
Execute the
raidcom reset command_status
command.
The error information of asynchronous command processing in the
storage system is reset.
2
.
Execute the asynchronous command.
3
.
Execute the
raidcom get command_status
command to check if all
asynchronous command processing is done or if no error occurred.
Asynchronous commands
The asynchronous commands associated with the
raidcom
configuration
setting command provide provisioning functions. The following table lists the
provisioning functions performed by asynchronous commands and describes
the required syntax. For details about
raidcom
command syntax, see the
Command Control Interface Command Reference .
