Solution Type Technical Instruction Sure Solution 1005170.1 : Sun StorageTek [TM] 6130/6140/6540: How to Change the Segment Size for a Volume Using CAM
PreviouslyPublishedAs 207258 Description This document describes the process to change the segment size of a volume using the Common Array Manager(CAM) or sscs CLI. Steps to Follow List out Current Profile for a Given Volume. Using CAM
Using sscs1. Get the profile name from the volume: sscs list -a array_name volume volume_name | grep Profile 2. List profile details: sscs list -a array_name profile profile_name 3. Note all settings for
Create a new profile with the desired transition segment sizeUsing CAM
Using sscsCreate the new profile based on the following options for sscs: sscs create -a arrayname -r RAIDLEVEL -s segment_size -h read_ahead -n #drives -k drive_type profile profile_name for example sscs create -a myarray -r 5 -s 256K -h off -n variable -k ANY NOTE: The segment can only transition by double or half the current value for the volume. For example, 256K can go to 128K or 512K only. Create a New Pool for This ProfileUsing CAM
Using sscssscs create -a arrayname -p new_profile pool new_pool_name example: sscs create -a myarray -p new_256K_profile pool new_256K_pool Change the Pool of the Volume to the New Pool NameUsing CAM
Using sscssscs modify -a array_name -p new_pool_name volume volume_to_be_modified example: sscs modify -a myarray -p new_256K_pool volume MyVol Review the Job CompletionUsing CAM
Using sscssscs list -a array_name jobs
NOTE: Only a single segment resize operation per volume may be executed, at a given time.
Internal Comments
Segment size changes are seen only at the volume level. This can be reviewed
