You can only specify one command target each time you run the health command.

Table 1. health command
Function	What it does	Command	Valid targets
Display health status	Displays the current health status of the command target. Return values are different for the BladeCenter and BladeCenter T configurations. Possible return values for the BladeCenter configuration are: ok warning critical Possible return values for the BladeCenter T configurations are: ok minor major critical	`health`	`-T system` `-T system:mm[x]` `-T system:blade[x]` `-T system:switch[x]` `-T system:power[x]` `-T system:blower[x]` `-T system:storagex] (for BladeCenter S units)` where x is the primary management-module, blade server, I/O module, power module, blower bay, or storage bay number.
Display health status for tree	Displays the current health status of the tree structure of devices present in the BladeCenter® unit, starting at the command target level. If management-module bays are part of the tree, they will be identified as primary or standby (redundant). Return values are different for the BladeCenter and BladeCenter T configurations. Possible return values for the BladeCenter configuration are: ok warning critical Possible return values for the BladeCenter T configurations are: ok minor major critical	`health -l` depth where depth `1` displays health status of the current command target `2`, `all`, or `a` displays a full tree display, starting at the command target level	`-T system` `-T system:mm[x]` `-T system:blade[x]` `-T system:switch[x]` `-T system:power[x]` `-T system:blower[x]` where x is the primary management-module, blade server, I/O module, power module, or blower bay number.
Display health status and alerts	Displays the current health status and active alerts for the command target. Return values are different for the BladeCenter and BladeCenter T configurations. Possible return values for the health status of the BladeCenter configuration are: ok warning critical Possible return values for the health status of the BladeCenter T configurations are: ok minor major critical Active alert information provides short text descriptions of alerts that are active for each monitored component. The total amount of information returned from the `health -f` command is limited to 1024 bytes.	`health -f`	`-T system` `-T system:mm[x]` `-T system:blade[x]` `-T system:switch[x]` `-T system:power[x]` `-T system:blower[x]` where x is the primary management-module, blade server, I/O module, power module, or blower bay number.
Display results with timestamp (BladeCenter E units only)	Adds display of timestamp information to status command output.	`health -t` Note: The -t option must be used with the -f option.	`-T system` `-T system:mm[x]` `-T system:blade[x]` `-T system:switch[x]` `-T system:power[x]` `-T system:blower[x]` where x is the primary management-module, blade server, I/O module, power module, or blower bay number.

Example: To display the overall health status of the BladeCenter T unit, while the BladeCenter T unit is set as the default command target, at the system> prompt, type

                  health

To display the health status of all components installed in the BladeCenter T unit, that are valid command targets, while the BladeCenter T unit is set as the default command target, at the system> prompt, type

                  health -l a

To display the health status of the blade server installed in blade bay 5, while the BladeCenter T unit is set as the default command target, at the system> prompt, type

                  health -T system:blade[5]

To display the health status and alerts for all components installed in the BladeCenter T unit, that are valid command targets, while the BladeCenter T unit is set as the default command target, at the system> prompt, type

                  health -l a -f

The following example shows the information that is returned from these commands:

               system> health
