Dealing with RAID Array Problems
This part of the chapter describes how to solve problems that might occur on your SSA
RAID arrays. You can get to the required SMIT menu by using fast path commands or
by working through other menus. During problem determination, you can use any of the
maintenance procedures described in Using Other Configuration Functions.
A hot spare disk drive automatically replaces a failed or missing disk drive in a RAID
array if:
v The Enable Use of Hot Spares attribute is set to yes.
v A hot spare disk drive is available.
When a hot spare disk drive starts operating, its Current Use attribute is changed from
Hot Spare Disk to Member of an SSA RAID Array. If a member disk drive of an array
fails, but access to that disk drive is still possible, its Current Use attribute is changed
from Member of an SSA RAID Array to Rejected. For all other changes to the use of
a disk drive, you must use either the ssaraid commands or the SMIT menus.
Notes:
1. Although this book always refers to the smitty commands, you can use either the
smitty command, or the smit command. The procedures that you follow remain the
same, whichever of the two commands you use. If you send the smit command
from a graphics terminal, however, the menus are displayed slightly differently from
those shown in this book. If you are not familiar with the selection of items from the
graphics versions of the menus, use the smitty command. The menus will then
appear as shown in this book.
2. If you use fast-path commands, you might need to go through intermediate steps
that are not shown in this book. Also, some menus might be displayed slightly
differently from those shown in this book.
