Hi,
I have the Lacie Big Disk, which is a external hard drive enclosure in a hardware RAID0 array of 2x250GB disks. The RAID controller seems to have died, leaving me with 2 working hard drives but no way to get the data. I tried hooking the drives up to a windows machine and using Raid... (4 Replies)
I have read anecdotes about people installing RAID0 (RAID - Wikipedia, the free encyclopedia) on some of their machines because it gives a performance boost. Because bandwidth on the motherboard is limited, can someone explain exactly why it should be faster? (7 Replies)
So I have 2 solaris sun servers one with a disk array with 14 drives which I need to move to the other server. How do I move the disk array configured as a Raid 5 to another server without losing data? So far I know I'll connect the drive, run devfsadm, use format to verify the server see's... (5 Replies)

Hello,
On 4/20/2018, we performed a disk replacement on our IBM 8202 P7 server. After the disk was rebuilt, the SAS Disk Array sissas0 showed a status of degraded. However, the pdisks in the array all show a status of active.
We did see a message in errpt. DISK ARRAY PROTECTION SUSPENDED.

lvmdiskscan - scan for all disks / multiple devices / partitions available
SYNOPSIS
lvmdiskscan [-d|--debug] [-h|--help] [-l|--lvmpartitions] [-v|--verbose]
DESCRIPTION
To give an overview about online peripherals usable to LVM, lvmdiskscan scans all SCSI, (E)IDE disks, multiple, loop and network block
devices in the system and lists them on standard output with name, size and type (text/hex). The size is the real device size, not the size
stored in the VGDA (See pvcreate(8) ) for details.
OPTIONS
-d/--debug
Enables additional debugging output (if compiled with DEBUG).
-h, --help
Print a usage message on standard output and exit successfully.
-l, --lvmpartition
Gives an overview about all LVM system identified partitions only.
-v, --verbose
Gives verbose runtime information about lvmdiskscan's activities.
DIAGNOSTICS
lvmdiskscan returns an exit code of 0, if disks / multiple devices / partitions where found and > 0 for error:
1 no special files found
2 no disks / multiple devices / disk partitions found
95 driver/module not in kernel
96 invalid I/O protocol version
97 error locking logical volume manager
98 invalid lvmtab (run vgscan(8))
99 invalid command line
