Adding a Disk Shelf to an Existing Storage Pool (CLI)
■
For log devices, click Log Profile and select either the mirrored or striped profile. If you
allocated an even number of log devices to the pool, select the mirrored profile.
Caution - A double failure can cause loss of data from a log in a striped configuration. It is
highly recommended to configure a mirrored log profile for added redundancy. For more
information, see “Data Profiles for Storage Pools” on page 111.
■
For cache devices, the profile is always striped, as shown under Cache Profile.

Adding a Disk Shelf to an Existing Storage Pool
(CLI)
Use the following task to add a disk shelf to an existing storage pool.
Before You Begin
■
For recommendations on how many drives to select per pool, as well as other considerations
and guidelines, see “Storage Pool Concepts” on page 109.
■
You must select the same data profile currently used in the existing pool. To understand the
different data profiles, see “Data Profiles for Storage Pools” on page 111.
■
If there is insufficient storage to configure the system for the data profile and its options,
some attributes may not be supported. For example, it is impossible to preserve NSPF
characteristics when adding a single disk shelf to a double parity RAID configuration with
the NSPF option. You can add the disk shelf, but cannot use the NSPF option.
■
Do not perform a pool configuration operation while a disk firmware upgrade is occurring.
To check if an upgrade is in progress, navigate to maintenance system updates.
Caution - Once a disk has been added to a pool, it cannot be removed without destroying the
pool entirely and losing all data.
1.
Install the new disk shelf using “Adding a New Disk Shelf” in Oracle ZFS Storage
Appliance Customer Service Manual.
2.
Go to configuration storage.
