A5x00 (photon) Cheat Sheet

Updated 12 Jul 2002 Read time 2 min(s) 42 sec(s) (2118 views). Storage

This article provides a quick guide to the supported disk configuration of Sun StorEdge™ A5000, A5100 and A5200 storage arrays.

The A5000 and A5100 are 14 disk arrays (7 disks in the front and back). The A5200 has a larger capacity of 22 disks (11 front and back). Both arrays have 4 fibre channel connections to it.

Check A5x00 status

# luxadm probe
sunhost# luxadm probe
Found
SENA Name:photon   Node WWN:5080020000000598
  Logical Path:/dev/es/ses0

Note the SENA Name name entry for the enclosure name

# luxadm display <enclosure-name>

Using the above probe output, we see an example:

Check A5x00 disk status

running format to check all disks are seen
running luxadm display [ <name>,<position> | <WWN> ] where
- <name> is the enclosure name gotten from the probe
- <position> is the position of the disk in the array. f=front r=rear, and the slot #. ie:
```
luxadm display photon,f10
```
  for photon's front slot 10 disk.
- <WWN> is the World Wide Name of the disk. This can be gotten from the device path: ~/ssd@Wxxxxxxxxxx,0 (the x's represent the string to be inputed in the command) ie:
```
luxadm display 20000020370d7d00
```
You may use this to find the disk firmware and path status to the drives.

Minimum Disk Configuration

# slots	comments
14	In the minimum disk drive configuration for the 14-slot disk array, disk drives are shipped in rear backplane slots `0`, `3`, and `6` as well as front backplane slots `3` and `6`.
22	In the minimum disk drive configuration for the 22-slot disk array, disk drives are shipped in rear backplane slots `0`, `3`, `6`, and `10` as well as front backplane slot `0`, `5`, and `10`.

Low-level troubleshooting

Q? Can format or luxadm display see the array and all disks?

If not can probe-scsi-all from OK prompt (see sunsolve srdb 13189), else contact Sun hardware support
If so then boot from a OS cd (OK> boot cdrom -sw) and check with format. if not, contact Sun hardware support
If so, then the device paths were wrong. (see sunsolve infodoc 15010) to rebuild the device path from the cdrom to original OS.
