There are two kinds of hot spare (standby) drives available in the Sun
StorEdge[TM] 6320: dedicated and global.
>A dedicated hot spare is only used for the pool in which it was
created. It can be added when creating a pool for the first time or when
modifying a pool using a profile that has a dedicated hot spare. You can
not add a dedicated spare to a profile that is in use.
>A global hot spare is used for the array that it is part of. A
global hot spare is added to an array. A global hot spare can be added at
anytime as long as there are unused drives, other then d1. The maximum
amount of global hot spares allowed in an array is 8.
To create a new pool with a dedicated hot spare:
Syntax:# sscs create -a array-name -t tray-id [-d number-of drives ] -r
RAID-level -s {0 | 1} pool pool-name
Example: # sscs create -a array00 -t 2 -d 4 -r 5 -s 1 pool hspool
The "-s 1" adds the hot spare.
You can then use a profile to modify the pool by removing or adding a hot
spare:
Syntax:# sscs modify -a array_name -p profile_name pool pool_name
Example:# sscs modify -a array00 -p joe pool hspool
In the example above, applying the "joe" profile to the hspool removes the
hot spare.
To create a global hot spare:
Syntax:# sscs modify -h hot-spare-drive-count array array-name
Example# sscs modify -h 2 array array00
The above example adds 2 global hot spares to array array00.
To add a global hot spare from the Configuration Services GUI:
1. Select "SE6000 Arrays" from the left column
2. In the right screen, select the array to which you are adding the
spare.
3. Click the Configure button.
4. Under the "Array array_name Properties" window, find the option "Array
Hot Spare Pool Size:", which lists the number of global hot spares
for this array.
5. Change the number of disks to increase or decrease the number of global
spares for this array.
6. Click the Save button to apply the change.
To add a dedicated hot spare from the Configuration Services GUI:
1. Expand the array list (array00, as used in the example).
2. Expand the pool list.
3. Select the pool to which you want to add the hot spare.
4. In the right window, click the "Apply Different Profile" button.
5. Select the profile from the displayed list. To view details of the
profile, click the profile name.
6. Click the Save button.
