Replacing, adding, and removing hardware, and upgrading firmware 8–22
7. Boot the new Object Storage Servers, as shown in the following example:
sfs> boot server south[5-6]
8. Configure the storage for the new Object Storage Servers and complete the configuration of the
servers, as described in the following sections of the HP StorageWorks Scalable File Share System
Installation and Upgrade Guide:
• For EVA4000 storage, refer to Sections 6.18.2 through 6.18.6.
• For SFS20 arrays, refer to Sections 7.15.2 through 7.15.4.
Note that, to fully configure the new Object Storage Servers, you must complete all of the tasks in the
specified sections.
9. Section 6.1 (of this guide) describes how to verify that a system has been installed correctly and is
operating normally. Use the instructions provided there to verify the operation of the new Object
Storage Servers and storage.
8.3.2 Removing Object Storage Servers
CAUTION: When you are removing Object Storage Servers from the system, you must first delete any file
systems that use those Object Storage Servers; as a result, all data on the file systems is lost.
It is possible to remove Object Storage Servers from an HP SFS system. Note the following points:
• You must first delete any file system that uses the Object Storage Servers you are removing.
• Because servers are organized in pairs, you must remove Object Storage Servers in pairs.
• You must also delete the storage that is attached to the Object Storage Servers from the
database.
The following instructions describe how to remove a pair of Object Storage Servers from an HP SFS system
that has six servers (an administration server, an MDS server, and four Object Storage Servers). You can
adapt the procedure to remove a number of pairs of Object Storage Servers at the same time:
1. Back up the database, as follows:
# sfsmgr
.
.
.
sfs> create database_backup
2. Save the backup file to an external system, as shown in the following example, where the full name of
the backup file is
/var/hpls.local/hplsdb_20040311-1041.tar.gz
, the external system
host address is
16.123.123.1
, and the account on the host is named
fred
:
# scp /var/hpls.local/hplsdb_200403011-1041.tar.gz \
[email protected]:/home/fred
3. Delete any file system that uses the Object Storage Servers you are removing, as shown in the
following example, where the
data
file system is deleted:
sfs> delete filesystem data
4. Shut down the Object Storage Servers that are to be removed, as shown in the following example:
sfs> shutdown server south[5-6]
5. Enter the
configure
system command, select the option for the
System
menu, and then decrease
the number of servers in the system (from six to four in this example), as follows:
sfs> configure system
This menu allows you to specify or update configuration data. If
you are not happy with any of the data you have entered, you may
reenter it again. Your changes do not take affect until you exit.
If you choose to quit, all changes you have made are discarded.
