Removing and Replacing an Advanced SerialRAID Adapter
Attention: The adapter assembly contains parts that are electrostatic-discharge
(ESD) sensitive. Use the tools and procedures defined by your organization to protect
such parts.
1. Remove the adapter from the using system (see the Installation and Service Guide
for the using system).
2. If you are exchanging this adapter for another, remove from it the SDRAM module
and, if present, the Fast-Write Cache Option Card. You must keep these items for
the replacement adapter card.
Note: The Fast-Write Cache Option Card, if present, might contain customer data.
v
See “Removing an SDRAM Module of an Advanced SerialRAID Adapter” on
page 329 to remove the SDRAM module.
v
See also “Removing the Fast-Write Cache Option Card of an Advanced
SerialRAID Adapter” on page 332 if you are removing the Fast-Write Cache
Option Card.
3. Install the SDRAM module and, if present, the Fast-Write Cache Option Card, onto
the replacement adapter card.
v
See “Installing an SDRAM Module of an Advanced SerialRAID Adapter” on
page 330 to install the SDRAM module.
v
See also “Installing the Fast-Write Cache Option Card of an Advanced
SerialRAID Adapter” on page 334 if you are installing a Fast-Write Cache Option
Card.
4. If the network into which you are installing this adapter is a two-way network and it
contains RAID-1 or RAID-10 arrays with coupled disk drives (see Chapter 7,
“Copying Data from Arrays and from Volume Groups” on page 149), go to step 5.
If the network into which you are installing this adapter is not a two-way network or
it does not contain RAID-1 or RAID-10 arrays with coupled disk drives, go to step 6
on page 328.
5. Attention: If the network into which you are installing this adapter is a two-way
network that contains RAID-1 or RAID-10 arrays with coupled disk drives, you must
do the following procedure. If you do not, the coupled disks might return to 0%
copied, or, if data sectors that are not valid exist in the array, the array might
become unavailable to the using system.
Before you connect the adapter to the SSA loop, ensure that the latest version
of adapter microcode is loaded onto the adapter, as follows:
a. Do not connect the external SSA cables to the adapter yet.
b. Switch on power to the using system, wait for the adapter to be configured. The
adapter microcode is automatically downloaded.
c. Connect the external SSA cables to the adapter.
d. Run the cfgmgr command.
