Configuring a Storage Array
defaultHostType
to Linux, the RAID controller module communicates with
any undefined host if the undefined host is running Linux. Typically, you
need to change the host type only when you are setting up the storage array.
The only time you might need to use this parameter is if you need to change
how the storage array behaves relative to the hosts.
Before you can define the default host type, you need to determine what host
types are connected to the storage array. To return information about host
types connected to the storage array, you can use the
show storageArray
command with the
defaultHostType
parameter or
hostTypeTable
parameter.
This command returns a list of the host types with which the RAID controller
modules can communicate; it does not return a list of the hosts. The
following examples show how to use the
defaultHostType
parameter and the
hostTypeTable
parameter:
client>smcli 123.45.67.89 -c "show storageArray
defaultHostType;"
client>smcli 123.45.67.89 -c "show storageArray
hostTypeTable;"
The following example shows how to define a specific default host type:
client>smcli 123.45.67.89 -c "set storageArray
defaultHostType=11;"
The value
11
is the host type index value from the host type table.
Setting Modification Priority
Modification priority defines how much processing time is allocated for virtual
disk modification operations. Time allocated for virtual disk modification
operations affects system performance. Increases in virtual disk modification
priority can reduce read/write performance. Operations affected by modification
priority include:
• Copyback
• Reconstruction
• Initialization
• Changing segment size
• Defragmentation of a disk group
