MSA 1000 / 1500: bringing up full disk speed again ?

Hello everyone,

perhaps it´s a very simple quetsion - but I did not find the answer yet:
Whe I do a "show disks" on the CLI of our MSA1500cs I get something liske that:
Disk List: (box,bay) (B:T:L) Size Speed Units
Enclosure 1: SCSI (0:06:00) PROLIANT 4LEE CP20
Disk101 (1,01) (0:00:00) 300.0GB 160 MB/s 0, 1, 2, 3, 4, 5, 6
Disk102 (1,02) (0:01:00) 300.0GB 5 MB/s 0, 1, 2, 3, 4, 5, 6
Disk103 (1,03) (0:02:00) 300.0GB 5 MB/s 0, 1, 2, 3, 4, 5, 6
Disk104 (1,04) (0:03:00) 300.0GB 160 MB/s 0, 1, 2, 3, 4, 5, 6
Disk105 (1,05) (0:04:00) 300.0GB 10 MB/s 0, 1, 2, 3, 4, 5, 6

etc....

Notes:
The speed is the currently negotiated speed to the disk. This may
be less than the maximum speed supported by the device due to bus
faults, loss of signal integrity, etc.

All the disks are the same make and model. So - for some reason some of the disks fell into a slower connection speed.

Which (CLI-)command brings the to maximum speed again ?

Best regards
Thorsten

As far as I know, there is no specific command to re-negotiate speeds. Last time I checked, there wasn't even a command to shutdown/reboot the controllers so you have to do a power-cycle...
