Configuring tiers and migrating data using the CLI

Use the ibrix_tier command to manage tier assignments and to list information about tiers.

Use the ibrix_migrator command to create or delete rules defining migration policies, to start

or stop migration tasks, and to list information about rules and migrator tasks.

Assigning segments to tiers

First determine the segments in the file system and then assign them to tiers. Use the following

command to list the segments:

ibrix_fs -f FSNAME –i

For example (the output is truncated):

[root@ibrix01a ~]# ibrix_fs -f ifs1 –i

SEGMENT OWNER LV_NAME STATE BLOCK_SIZE CAPACITY(GB)

------- -------- ------- ----- ---------- ------------

1 ibrix01b ilv1 OK 4,096 3,811.11 . . .

2 ibrix01a ilv2 OK 4,096 3,035.67

3 ibrix01b ilv3 OK 4,096 3,811.11

4 ibrix01a ilv4 OK 4,096 3,035.67

Use the following command to assign segments to a tier. The tier is created if it does not already

exist.

ibrix_tier -a -f FSNAME -t TIERNAME -S SEGLIST

For example, the following command creates Tier 1 and assigns segments 1 and 2 to it:

[root@ibrix01a ~]# ibrix_tier -a -f ifs1 -t Tier1 -S 1,2

Assigned segment: 1 (ilv1) to tier Tier1

Assigned segment: 2 (ilv2) to tier Tier1

Command succeeded!
