+SAS Disk Array Management
+Cause
+- General Help:
+# sissasraidmgr -h
+- Viewing the Disk Array Configuration:
+# sissasraidmgr -Ll controller_name -j1
+- Preparing Disks for Use in SAS Disk Arrays:
+# sissasraidmgr -P -z disk_list
+(For example, # sissasraidmgr -P -z hdisk1 hdisk2 pdisk3 pdisk4)
+- Changing pdisks to hdisks:
+# sissasraidmgr -U -z pdisk_list
+- Creating a SAS Disk Array:
+# sissasraidmgr -C -r raid level -s  stripe size -z pdisk_list
+- Deleting a SAS Disk Array:
+# sissasraidmgr -D -l controller name -d array_name
+- Adding Disks to an Existing Disk Array:
+# sissasraidmgr -A -l array name -z pdisk list
+- Creating Hot Spare Disks:
+# sissasraidmgr -H -z pdisk_list
+- Deleting Hot Spare Disks:
+# sissasraidmgr -I -z pdisk_list
+- Displaying Rechargeable Battery Information:
+# sissasraidmgr -M -o0 -l adapter_name
+- Forcing a Rechargeable Battery Error:
+# sissasraidmgr -M -o1 -l adapter_name
+- Recovering from Disk Failures:
+# sissasraidmgr -R -z pdisk_list
+- Viewing the SAS device resource locations:
+# sissasraidmgr -Z –o0 –j3 -l adapter_name
+- Viewing the SAS device resource information:
+# sissasraidmgr -Z –o1 –j3 -l adapter_name
+- Viewing the SAS path information for the attached device:
+# sissasraidmgr -T –o1 –j3 -l device_name
+- Viewing the SAS path information graphically for the attached device:
+# sissasraidmgr -T –o0 –j3 -l device_name

+==== Unable to see an hdisk ====
+After replacing a disk, you don't see an available hdisk, it stays defined
