This page describes administering the PowerEdge RAID Controllers (PERC) in CSE's recent Dell servers.
In the [distant] past, Dell's RAID controllers used LSI chips. LSI was subsequently acquired by by Avago/Broadcom. Very possibly the chips still come from LSI/Broadcom, but the command-line utilities from LSI/Broadcom (megacli and, later, storcli) which could be used to examine and change the configuration of earlier Dell PERC controllers no longer detect the Dell's controllers. Instead, there's a Dell-specific tool called perccli64 which needs to be downloaded from Dell's website. perccli64 looks extremely similar to storcli.
Installing the binary in /root/bin
- Download the latest "LINUX PERCCLI Utility For All Dell HBA/PERC Controllers | Driver Details" from Dell's website...
- E.g.
PERCCLI_7.2313.0_A14_Linux.tar.gz
- E.g.
- Untar the file:
tar zxf PERCCLI_7.2313.0_A14_Linux.tar.gz
- Change to the created directory:
cd PERCCLI_7.2313.0_A14_Linux/
- Unpack the deb file:
- ar x perccli_007.2313.0000.0000_all.deb
- Untar the file containing the actual binary:
tar --xz -xf data.tar.xz
- Move the binary into place:
mv opt/MegaRAID/perccli/perccli64 /root/bin/
- Enjoy!
Useful commands
perccli64 help
Displays help. Very concise.
It's notable that:
/cx refers to the controller a command should apply to. Replace 'x' with the controller number (see perccli64 show all (below).
/ex refers to the enclosure attached to the specified controller. Replace 'x' with the enclosure number (see perccli64 /cx show all (below).
perccli64 show all
Lists all the PERC controllers found.
perccli64 /cx show all
Outputs details about the specified controller. Lots of detail. Includes a list of attached enclosures, a list of all physical disks in each enclosure, the RAID configurations of these disks, disk statuses, RAID statuses, etc.
perccli64 /cx /ex show [all]
Outputs some detail about the specified enclosure. Includes the number of physical disks in the enclosure.
