Adding disks to a storage pool

You can add SSDs to an existing storage pool and increase its cache size by using Storage Manager .

Before you begin

Both nodes of the HA pair must be up and running in order to allocate SSDs and SSD spares through a storage pool.

About this task

  • The SSDs that you add to a storage pool are distributed proportionally among the aggregates using the storage pool cache and to the free space of the storage pool.

  • Storage Manager enforces the hot spare rule for SSD RAID groups when you use SSDs for adding disks to a storage pool.

    For example, if there are 10 SSDs in the SSD RAID group and the option raid.min_spare_count is set to 1 at the node level, Storage Manager leaves 1 SSD as the hot spare and uses the other 9 SSDs for SSD-related operations.

  • You cannot use partitioned SSDs when adding disks to a storage pool by using Storage Manager.

  1. Click Storage > Aggregates & Disks > Storage Pools .
