Replacing Two Feature Storage Cards

To replace two feature storage cards with ACSLS, perform the following steps:

Log in as user acsss and enter the following command to shut down the ACSLS application running on the feature card:
```
acsss shutdown
```
Physically remove the feature storage cards to be replaced.
Insert the replacement feature storage cards into the same locations.
Apply a new external label to the replacement feature storage cards. Include an appropriate name that reflects the changes made.
Extract the feature card scripts as described in Installing ACSLS on the SL4000 Feature Card:
See "Step 4: Extract the ACSLS Feature Card Scripts".
Ensure network, host name, DNS, and other network-related settings are established.
The ACSLS recovery process maintains as many settings as possible. Verify bond3 network connectivity and ensure that your IP address, host name, and related items are correct using the hostname command, ping command, and others as required. If you encounter issues, then review applicable steps as described in Installing ACSLS on the SL4000 Feature Card:

See "Configuring the Feature Card and Preparing for ACSLS Installation".

Note:
If you need to change your IP address, host name, or other network-related information as part of this task for feature card replacement, you must redo these steps.
Verify that the feature storage cards are initialized as described in Installing ACSLS on the SL4000 Feature Card:
See "Step 5: Insert and Initialize All Feature Storage Cards".
As user root, issue the following commands to remove remnants from the previous ACSLS installation:
```
rm -rf /opt/ACSLS/ACSLS_8.5.1
userdel acsss
userdel acssa
userdel acsdb
userdel postgres
yum remove ACSLS
yum remove PostgreSQL
```
You may need to kill errant processes if they prohibit successful execution of yum removals. It is important that ACSLS and PostgreSQL are successfully removed.
Extract the ACSLS software bundle as described in Installing ACSLS on the SL4000 Feature Card:
See "Step 10: Extract the ACSLS Software Bundle".
Perform the steps described in Installing, Configuring, and Running ACSLS on the Feature Card.
Restore the ACSLS database from the most recent backup or an accessible backup location:
1. As user acsss, run db_restore.sh:
```
su - acsss
cd /bin
./db_restore.sh latest
or
./db_restore.sh/bkupb/<DB_SNAPSHOT_FILENAME>
```
  Substitute the specific file name of your backup for latest and <DB_SNAPSHOT_FILENAME>.
  
  Redundant copies of recent backup files reside under /bkupa, /bkupb or /bkupc. If no ACSLS database backups are available to you locally, you may want to pull the latest database backup from your remote backup server. If you do not want to use an existing database backup, and would rather create a new one, then run accss_config instead.
2. Once you have restored the database or created a new database version, re-start ACSLS as user acsss:
```
su – acsss
```
