Creating a Hardware Disk Mirror Perform this procedure to create an internal hardware disk mirror configuration on your system. Verify which disk drive corresponds with which logical device name and physical device name. See: ■ “About Physical Disk Slot Numbers, Physical Device Names, and Logical Device Names” on page 117 ▼ To Create a Hardware Disk Mirror 1. To verify that a hardware disk mirror does not already exist, type: # raidctl No RAID volumes found. The example indicates that no RAID volume exists. In another case: # raidctl RAID Volume RAID RAID Disk Volume Type Status Disk Status ------------------------------------------------------ c0t4d0 IM OK c0t5d0 OK c0t4d0 OK The example indicates a hardware mirror has degraded at disk c1t2d0. Note – The logical device names might appear differently on your system, depending on the number and type of add-on disk controllers installed. 118 Sun Fire V445 Server Administration Guide • August 2006
2. Type the following command: # raidctl -c master slave For example: # raidctl -c c1t0d0 c1t1d0 When you create a RAID mirror, the slave drive (in this case, c1t1d0) disappears from the Solaris device tree. 3. To check the status of a RAID mirror, type the following command: # raidctl RAID RAID RAID Disk Volume Status Disk Status -------------------------------------------------------- c1t0d0 RESYNCING c1t0d0 OK c1t1d0 OK The example indicates that the RAID mirror is still resynchronizing with the backup drive. The example below shows that the RAID mirror is completely restored and online. # raidctl RAID RAID RAID Disk Volume Status Disk Status ------------------------------------ c1t0d0 OK c1t0d0 OK c1t1d0 OK Under RAID 1 (disk mirroring), all data is duplicated on both drives. If a disk fails, replace it with a working drive and restore the mirror. For instructions, see: ■ “Performing a Mirrored Disk Hot-Plug Operation” on page 121 For more information about the raidctl utility, see the raidctl(1M) man page. Chapter 6 Managing Disk Volumes 119
